i do agree somewhat, though i disagree about the major problem with UMD, i believe was it made the psp much larger physically that it should of been (it struggles to fit in a pocket, unlike the nintendo ds ).
The 4" screen is as much to blame as anything in that regard. The machine would always be as long as it is, and any thinner, it'd be just plain fragile. The only way round that I think is a clamshell design.
personally they should of made games on a ROM memstick, sure it would of been f'in expensive in the start, but they would be reaping the benifits now + in the future (and also pushing downloadable games heavily which are nearly costfree)
Expensive to the point no-one would buy it and it'd have no software developed for it, so by the time Flash was cheap enough to make it worth having, the platform would have died. Plus if the games are downloads only, why are stores going to sell PSPs? "Come buy this PSP from us. It cost $500 as it uses Flash storage, there's no games for it as no-one buys a $500 handheld, and once you ahve bought it, we're not going to make any profit from software for the platform. Hang on. Why not stock DS instead where we'll have an install base and games to sel them..."
ive gotta disagree about the tv-out though, i cant see the worth of that, u can buy portable dvd players for next to nothing (which i assume some have tv-outs) + would have better picture quality, dvds having ~8gb storage.
Quality wise, the difference might not be great. Though they have 8 GB storage, they don't use it. This is what surprised me. My friend has ripped 50 DVD movies to his MPC, and he was showing me that only half the disk is used. 4-5 GBs is the average for movies. Because that's at MPEG2, even though 1.5 GB is much less, using a more modern codec better suited to low bitrate movies, the difference should be minimal.
As for portable DVD players, if you have to carry one as well as your PSP, that's an extra device to lug around. If PSP had TV out for movies, it'd be one more reason to take it with you to your friend's house, or on holiday. Without TV out, it's only good for personal entertainment. Opening it to group experiences greatly increases value and exposure.
