Welcome to a laptop battery specialist of the IBM Laptop Battery
At the moment - the Google Nexus One is the best there is for people on T-Mobile or AT&T in the U.S. Of course, "the best" can change in a matter of weeks, when the next new phone is released.
Inside the Nexus One is a 1GHz processor, a 5 megapixel auto-focus camera (with flash) and a really stunning OLED display with 800x480 pixels (which is not very good in direct sunlight). The phone has GPS, a compass, accelerometer, and worldwide 3G support. Best of all - the GPS and compass are put to amazing use inside Google maps street view - simply start the app, and point your phone around - it'll show street views based on what it is looking at.
The phone looks good, feels good, and has enough power to handle anything I throw at it. Memory expansion comes from a MicroSD card - 16GB cards can be found for just $40, and 32GB cards are on their way. Oh, and I can obviously invest in a spare battery like IBM 08K8198 Battery , IBM 08K8197 Battery , IBM 92P1075 Battery , IBM ThinkPad R40 Battery , IBM ThinkPad R32 Battery , IBM 02K6928 Battery , IBM 02K7054 Battery , IBM ThinkPad A20 Battery , IBM ThinkPad A20M Battery , IBM ThinkPad A21M Battery , IBM ThinkPad 240 battery , IBM ThinkPad 240Z battery , because unlike some brands, Google doesn't mind me removing the back panel to replace my own damn battery.
