well at the 250 price tag and sony hopefully having common sense to not region lock a portable console thats big use is plane flights i will be having one in my bag to play on train home and while at uni.
If i payed big for the ipad thats dam expensive i would of played it like a game console anyways and its too big and impactical for me and any student, when you could buy a macbook pro instead.
this cheap pocket rocket is far better than burning my battery on my smart phone. Only problem i have is that 1. the games are going to be too expensive. Free app ad supported games, 1-5 dollar app games are required on the store alone with more upmarket app game 5-15 dollar game, then the full games that run for 15-30 dollars with 30 dollars USD being the max for games like uncharted.
If they screw up the pricing and not have those cheap app games to compliment the bigger titles then the system will fail. SONY can capitalise by having low prices and a good competitive store to that of the itunes then they have a real good chance of taking a chunk of the tablet market.
Also they should get google to create them a android platform for the device and allow other apps on there so it becomes the smaller, cheaper tablet.
Of Course That's Just My Opinion, I Could Be Wrong
