1 - He's calling it too expensive, but didn't seem to even NOTICE the $250 model, he only mentions the $300 model. Even if he did notice the $250 model, the PSP and 3DS started on that price, but I never saw any Gamepro article complain about that.
2 - PSOne and UMD Passport complaints? Really? You buy a brand new system, and you think a major flaw is you can't play games on it which you can already play now in portable form (PSP)?
3 - Weak Launch titles - Uncharted, Modnation, Little Deviants, Everybody's Golf, Motorstorm, WipeOut 2048 etc. That covers pretty much every one of the best selling/best rated game types on PS3 (Little Deviants is an original IP, points for that). You're entitled to your opinion, yes, but when your opinion esentially hates all the top rated game series on PS3, that's your own problem, you shouldn't write an article essentially stating you're right and the vast majority of gamer's opinions on those game series are wrong.
4 - Low Battery Life I somewhat agree with, it's pretty low.... but exactly the same as the 3DS for gaming. I'd be curious to see what he thought of the 3DS's battery life before it launched. If he thought it was even acceptable, that would clearly show he's just a Nintendo fanboy/Sony hater.
5 - Save Game managment, I have no clue about that, cannot comment due to the fact there's nothing publically known about it.
