iPod Touch or Zune HD Portable Media Player Recommendation?

[larrewl]

I want to show videos converted from HD (on my Windows XP PC) of my daughter's concerts on a high-quality 3-4" display on an inexpensive (<$200) player.
I want something to fit in my pocket and am considering:
1) iPod Touch, or
2) Zune HD.
Does anyone have any experience or recommendations? Any opinions are greatly appreciated.
