Looking for a device for portable video and internet access. Was considering a smartphone, or even a ipod touch or simmilar device. at the most i want to spend around $500. Now i see the subnotebooks like the Asus eepc and such at a close price and very verisitile since they can run windows.

For video playback, a large portion of what i watch is hard-encoded with subtitles, so video playback has to be very clear, since otherwise i worry the subititles might not be easily legible.
things i want:
video playback (mostly divx or easy to convert from divx to a compatible format
full web browsing, not the semi-web you get on cellphones
maby some basic game playing.

touchscreen (not necissary, but would really enjoy)
wifi (possibly bluetooth too)
possibly TV tuner/dvr (some archos and RCA models have this, but could easily get a $50 USB addon to a windows unit)
