MyMPx.org - What are you looking for in a new MP4 player?

If you were to get a new MP4 player, what features would you look for in the new MP4 player?

For me, with the increasing popularity of Wi-Fi, I would like to see a MP4 player with wireless. The one thing that really annoys me is having to look around for USB cable to connect it to my computer so I can copy songs to it. It would be so much easier to have it connect to my existing wireless so I can copy it directly through wireless to my player from my computer. No one really uses modems now so most of the computers have a network card in it. Wireless/broadband routers are very common now so it just makes so much more sense.

It would also solve issues with the cheap (highly faulty) USB cables that come with the players as well.

That would be my first requirement - to have wireless on my MP4 player.
