I'm not quite sure on the size (guessing 42" at least), it's a bit of a long story. It's 720p, which is not incredible, but better than the nothing I have now (well, I do have a broken 1080i olde HDTV that lacks cross-conversion capability, but again, it's broken).
Short version: they are closing my office and setting us all up with home offices since we all work on the internet anyway, and it will save them lots of money by not having to pay a corporate lease. They have to get rid of everything they can't transfer to another site, which includes a pair of HDTVs they used (read: never actually got used) for video conferencing. I lucked out in the raffle, so even though the TV is ~6 years old, it's barely been used.
