Last week, a passel of leaked PowerPoint slides appeared to give a sneak peek of Microsoft's plans for Windows 8.For information go to the dailybattery . (I should call them "alleged Microsoft PowerPoint slides" or something, but Mary Jo Foley and Ina Fried are accepting them as the real deal-and that's good enough for me.)

Among the features mentioned: A new technology for superfast startups (a perennial boast of new versions of Windows dating at least back to Windows 98), multiuser login via face recognition, an improved help system, and a tool for restoring Windows to its original settings without munging your data. The company would apparently like to help PC makers build machines that have some of the "it just works" reliability associated with Fujitsu Lifebook T5010 Battery, (It turns out that consumers are willing to pay for a better experience-apparently, the price premium that Apple commands is about more than unicorn tears.)

It would be a mistake to take the leaked slides as a definitive guide to the upcoming OS: Windows 8 is still early in the development process, and the details in the deck were prepared to address early questions from hardware types, not to serve as an overarching prospectus. And Microsoft's early pitches for forthcoming versions of Windows usually haven't been a terribly reliable predictor of the products it's actually shipped-just ask anyone who took the initial scuttlebutt about Vista very seriously, lilke the sony .

But thinking about Windows 8 left me mulling over what I'd like to see when the the OS (which may well be called something other than Windows 8) arrives. Here's my quick wish list-I'm assuming that Win 8 will still be recognizably Windowsesque rather than an utter reimagining for the Web era... A Windows that's like Windows 7, only more so. Windows 7's streamlined simplicity and emphasis on staying out of your face makes it one of the best Windows updates company with all kinds of computers battery , you have a lot of choice .But lots of opportunities remain to take the same idea further, and to fix remaining annoyances. One thing that drives me bonkers: If an application in the Taskbar is trying to alert me, the Taskbar won't minimize even if I've set it to automatically hide itself...which often leaves it covering up the bottom of an application I'm working in. The alerts are rarely urgent, and it's sometimes tough to figure out which app is doing the alerting. So when I set the Taskbar to autohide, I want it to autohide. Period dell the same .

All in for tablets, or not at all. The leaked slides talk about Windows 8 being designed to run well on three primary types of computers: laptops , all-in-one desktops, and slates (aka tablets). It's the last category that worries me. I'm not convinced that it's possible to design a top-notch tablet OS unless it's designed only to run on tablets-and 98% of existing Windows software assumes the existence of a physical keyboard and a mouse. Suggestion to Microsoft: Build excellent tablet-friendly versions of Office and other key apps, and devote a ton of effort to helping third-party developers tabletize their programs. More Web integration. Google Chrome has a clever feature which lets you iconize Web apps like Gmail so you can launch them from the Start menu and they look more like traditional apples .

Microsoft should swipe the idea and build it into Windows-and pursue other ways to blur the lines between desktop software and Web-based service a lot more than it's done to date. Some silver bullet for security management hassles. On a day-to-day basis, the single biggest difference between using a Windows computer and a Mac isn't that Windows types are more likely to suffer devastating security breaches. It's that they spend more time futzing with anti-virus utilities and other security software. The worst ones are a horrendous timesink, and even the best ones demand more of your attention than they should. I'm not sure what Microsoft can do here, but I think it would be very much in its own self-interest to address the ongoing drudgery of Windows security. No half-baked features. , sony battery like VGP much more than Apple, has a tendency to add stuff to operating systems that never lives up to its potential and sometimes turns, over time, into annoying cruft. (Windows 7's Device Stage leaps to mind.) Fewer but better features wouldn't be a bad mantra for the upgrade. A really good version of Internet Explorer. Yes, it's easy enough for anyone who wants to switch to Firefox, Chrome, Opera, Safari, Flock, or any other browser to do so. But the teeming masses who will use whatever browser Microsoft provides deserve to flourish, too-and technical advancements like HTML5 can't change everything unless IE supports them.

Microsoft's technical previews of Internet Explorer 9 look impressive, but it still hasn't released a full-blown IE9 beta-so it's premature to form any real opinions about the browser that's likely to come bundled with Windows 8. Data recovery done right. The backup features built into Windows are usually disappointing. Or they don't come with every version of the operating system. Or both. First-rate data protection should be an unalienable right of operating system users. I'm not saying Microsoft should clone Apple's Time Machine-it's not free of its own gotchas-but it should take the challenge as seriously as Apple did. Okay, that's enough wishing for now. Got any additions for this list-either mundane practical ones or pie-in-the-sky stuff?

Perhaps no common computer product has as many variations, with as wide a performance range, as the modern laptop battery . From tiny netbooks to big and powerful desktop-replacement systems, the differences in pricing, features, and performance are staggering. Follow our comprehensive guide to make sure you get the laptop battery that's right for you.

Buying a new loptop battery can be tough because you have so many options to consider, and no shortage of reasons for purchasing one. Maybe you're about to head off to college and you need to take notes in class. Perhaps your current laptop labors when running today's applications, and it's time for an upgrade like Fujitsu Lifebook P1620 Battery . Or maybe you're happy with your desktop PC, and you want a companion device for surfing the Web from your couch. Even if you know what you want to do, with so many laptop models available it can be hard to decide among them. The potential for confusion is enough to make you choose something that just looks cool or happens to be available on your warehouse store's shelf--but that approach can end in heartache.

It's best to start by deciding which category of Fujitsu laptop battery you're most interested in. Laptops fall into four main categories: netbooks, ultraportables, all-purpose laptops, and desktop replacements. The laptop category that is right for you depends on the kind of user you are. Once you have decided on a category of laptop, it's time to start considering the specs.

If you're sick of using an MP3 player that frequently runs out of battery power, the Lenovo IBM Thinkpad X200 battery is for you. Featuring an audio-playback time of 30 hours, this sleek MP3 player also plays videos, offers an FM transmitter, and provides a voice recorder.

The Lenovo 3000 N200 battery measures 3.5 by 1.5 by 0.25 inches (about the same size as a fifth-generation iPod Nano) and has a 1.8-inch, full-col Lenovo 3000 C200 or , as well as a nifty touch-panel keypad. With a slick black-and-chrome encasing, the player is fairly attractive (it looks a lot like the first- and second-generation iPod Nanos). Unfortunately, it attracts fingerprints like nothing else; the touch panel, integrated into the casing, is a smudge magnet, too. The power/lock switch is on the side, while the volume buttons, fast-forward/rewind controls, and OK and Menu buttons are on the touch panel. The touch panel is incredibly responsive--so much so, however, that I ended up accidentally brushing it and changing the song as I was reaching over to press the lock button. Lenovo 3000 V100 battery through the included earbud headphones is decent, offering good bass and full sound.

Though the results are much cleaner on higher-quality headphones (I tried Lenovo 3000 Y410 Replacement Laptop Battery ), the bundled earbuds are better than most, and certainly superior to Apple iPod earbuds. The player has an equalizer (the only sound-setting option, as far as I can see) that includes Normal, XBass, Rock, Jazz, Classical, and Pop settings. Video playback is decent, considering that the screen is just 1.8 inches. The player comes with Sony VGP-BPS13 battery 3 for turning regular video files into the supported .smv format. The ArcSoft program, which took about 25 minutes to convert a 30MB file in my tests, is not compatible with certain codecs, such as Sony VGP-BPS13A/B battery and Xvid. The screen resolution is only 128 by 160 pixels, but video playback is smooth and seamless.

The menu is fairly simple and easy to navigate, once you get the hang of it. The only aspect I found unintuitive was that in vertically oriented menus you still have to press the fast-forward/rewind buttons to scroll up and down (because the volume buttons are dedicated only to that function, and don't double as scrolling controls). You can add music and pictures to the player by dragging and dropping the files in Windows Explorer or by Sony VGP-BPS9 through Windows Media Player. Supported formats include MP3, WMA, and OGG for audio, and JPEG and BMP for pictures. You can't sync playlists from Windows Media Player, however. In addition to the earbuds and the ArcSoft Media Converter 3 software, the HV18A-4G comes with a USB 2.0 cable, plus 35 free eMusic downloads and one free audiobook download (with a 14-day trial subscription to eMusic).

The touch panel is just a bit hypersensitive (luckily, the device has a hold button), but otherwise the affordable Haier HV18A-4G is a decent little MP3 player with great battery life. The main thing that holds this device back is its small capacity--it's available only in 4GB and 8GB versions, neither of which is enough space for most people's music and video libraries.
