Welcome to a laptop battery specialist of the Acer laptop battery
Travel with the Lenovo Ideapad S10 is quite comfortable - the machine is light, powerful enough for most tasks and with its built in webcam you can use chat applications like Skype or AIM.
It's small size makes it perfect for using in-flight, and you won't run the risk of snapping it in half when your fellow passenger decides to recline his or her seat in front of you.
Other machines often include a (very) basic case, but you'll have to find one of those yourself for the S10. I recommend the Solo Netbook Messenger pictured here on the right.
Power for the S10 comes from a 3 cell Lithium-Ion battery such as Acer Aspire 5920 battery , Acer Aspire 8920 battery , Acer BATBL50L6 battery , Acer Aspire 3100 battery , Acer TravelMate 2490 battery , Acer TravelMate 4200 battery , Acer BATBY27L battery , Acer BTP-550P battery , Acer BTP-25DI battery , Acer Travelmate 345 battery , Acer GRAPE34 battery , Acer Extensa 5210 battery pack, which brings me to the only real complaint I have about the machine - battery life is pretty limited. In its defense, no other 3 cell powered netbook is any better.
