What I would really, really like to see... Is the ZuneHD capable of DLing/playing Xbox classics from Live(or allow you do transfer them from your old disc via a 360). I mean, a 700mhz processor/128mb of ram shouldn't be a big deal to replicate the original Xbox, and then it instantly has the best hand-held library available. Just need to find a way to replace the sticks with something compact that can be on a hand held.
If this happens, it will be a Day 1 purchase for me. And it has huge upsides for MS. I mean, it suddenly makes a couple hundred old titles relevant again, and each sale would be pure profit. Developers would love them for it, opening up a new audience for games they've already made... and how many great old Xbox games that you never got a chance to play (or would replay) if they became portable? Who wouldn't play through Halo:CE again while riding the bus... or Ninja Gaiden? Who wouldn't finally give Psychonauts a chance since everyone says its great? It's a scenario full of win. (oh yeah, and it'd play music/videos too I guess)
Edit: Just saw the announcement about the ZuneHD... scratch that.
