Is this the one that's going for really cheap right now? If so i would be very interested to hear what you make of it. As far as i can tell however it only has a 3 cell battery which would indicate it would probably not last as long as the others mentioned in this thread. I need it to last about 5 hours a day on battery. However what do you use it for, i just need to know if it'll handle reasonable sized spreadsheets basically.
I've not used it for spreadsheets and I don't have Excel installed. If someone can point me at some sort of free spreadsheet software that'll cleanly uninstall I'm willing to have a bash on it though.
Oh, and yes its the cheap one. I paid a higher price for mine from a high street retailer as my main PC was borked at the time and a week of no internet was driving me mad, but I've heard they can be picked up for <£200.
