Honestly guys its about necessity more so than anything else.
You CANNOT have a physical disk drive on a handheld, without it being gigant and powerhungry.
I think the idea of haveing the same "medium" for both the handheld and the consol, is brilliant.
"take your games with you on the go".
(no compromises, its the same game, on the handheld as on the consol. To me thats a huge selling point)
(as a consumer you wont have to buy differnt versions of the same game, if you want to play on one or the other, or have to choose between them)
***** OBS : brillient idea = make it so you can share "save game data" between your consol and handheld... BOOOOOOM.
You can now play the same game at home in front of a tv, then contiune on your handheld from the exact same place you left off, before leaveing for work/school ect.
Developers will love you for it:
You wont have to develop the game for the consol and then port it to the handheld.
(double the market penetration, both handheld and consol sales for 1 game)
You wont have to have 2 productions for the same game.
(mass production => cheaper than haveing 2 productions running for every game made for your system.
