I can't see the appeal of watching TV/films on a screen the size of a postage stamp, myself.
They make psp's that small!? jkjk, i would go with a pocket pc, just cause you might be able to write programs on it with bmax in the near future (prolly not, but still, as for media.. i would probably go for the psp, cause of a bigger screen).
