I have an old
Dell Latitude CPx laptop where the battery is shot, lasts about half an hour normal use, but it works well enough apart from that. I'd let you have it with a PCMCIA network card and Linux installed for 30 euro, or something near there with a couple of Tegernseer Helles thrown in. With a bit more memory in it it will work fine for most general stuff, I used it for web browsing and simple office stuff and should anything go wrong there are a wide variety of
cheap replacement bits available on eBay.
PM me if you're interested, or wait for some smart arsed TTer to put some post saying you can get something better for less.
