Welcome to the club
the 3cell lasts about 3hrs (remember its small and sits flush with no buldges sticking out). havent got the official 6cell battery 'yet' but i guess that will last about 6hour 'ish. i have the 9cell! and that lasts 10hrs
as you may of guessed i need a lot of juice of the road and now i get a full day or even 2 days usage without worrying about being plugged in somewhere.
Lenovo S10e is indeed a sweet little network has almost no faults. All the hardware works great and even the pre-installed xp (with linux splashtop) is bloat-free and good to go straight out the box. Which leads me to my one and only gripe with this device, which is the fan is a little erratic... BUT! many users have reported this to Lenovo and they are working on a simple bios fix, so hopefully this will be resolved soon.
Theres some handy things which you can use the ExpressCard34 slot for. 3G internet, DVB TV/Radio, firewire, usb hub, ssd, sata2, esata. So i think this more then justifies losing 1 usb slot.
Let us know what you think of yours?
Enjoy
