I have a lifebook, 9 inch, about as big as a book, about as wide as a CD. Not too powerful, only got a 800mhz cpu running mostly at 300, and 256 ram, but its enough to run XP and word and other programs well. I love it, has a touch screen too. Battery lasts roughtly 5-8 hours, depending on what you are doing. Really cheap second hand, like 1000 AUD, like 650ish US off ebay (if you can find them).
They are much like the 9 inch vaio picturebooks that sony but better battery and touchscreen and inbuilt wireless, but no camera.
He is an ebay link that might give you an idea about it... every expensive link however:http://cgi.ebay.com.au/NEW-Fujitsu-L...QQcmdZViewItem
There was some really great pictures I found before comparing its size to objects:
Its a bit longer about as along as a American Dollar bill, about * 2 times as wide (not sure)
About 1.5X the width of a cd, about 2 twice as long.
I really love it and its just great, mine has a 30 gig hard drive and is powerful enough to watch DIVX movies on, so it makes a great machine to take on trips for music and movies. Only bum thing is no CD drive but i hardly use CD's anymore, just rip them to the hard drive and its perfect to stream stuff aswell, the 11 B wireless is enough to stream files off my 9300. It sucks bad at gaming, can't run anything really, great for emulation of GBA, SNES and SEGA stuff
No 3d stuff but, can't even run Counterstrike 1.6 at above 15 FPS.
Overall it is a great machine to have at school, fine you pick up and not worry about battery, the screen is big enough to read, and its keyboard is big enough to type on easily. Been using it all year, and well worth the money.
