I got my iPad in May 2010 and it still works fine, including (amazingly), the battery. Except of course, the software has become useless. YouTube doesn't work unless I do special URL mangling in the browser, which crashes every 2 seconds anyways. The latest OS release is so old it's from the days when Apple had a YouTube app, which Google later shut off the API for.
I really feel it deserves a second life running some kind of alternate OS and can think of several uses for it, but last I checked there wasn't much of that happening.
