Worth trying Linux Mint on it. I have a Toshiba NB100, cost buttons secondhand and came with Win 7 which was sslllllloooowww.... Probably due to the Windows update issue (sends CPU to 100% whilst doing nothing, for hours) fix now available for this, but I got bored and stuck Mint on it. If all you need it for is web surfing and office stuff it's absolutely fine. Even got Google Drive working on it this week, slightly faffy (Dropbox works out of the er..... box) but after a Google and a couple of code lines, it works fine.
