Well its owned by console users so the whole "why isnt it 69p" thing doesnt exist on this platform. The fact it also plays full priced games means it should stay that way. This means it might even be a bit of a haven for indie developers who can taget there games at gamers (because you are almost definately a gamer if you have a vita but an iPad user more likely not). You can prob charge a little more and seeing as the audience is looking for games you might sell just as well.
We all know there are tons of devs on IOS that dont sell much because of factors like a flooded market, 69p ($0.99) culture etc etc. So in theory it could be a very attractive place for indie devs.
Not saying it will be but it definitely has the potential.
Hopefully it will also have plenty of apps eventually like BBC iPlayer, IMDB, TV Catchup, steam app etc etc and even possibly pc remote play if its allowed. If Sony really let devs have there way with this thing it should really stop the need for hacking it and make it the ultimate gamers tablet.
Also please someone make a better web browser. Just want portrait view, copy/past and proper video support and il be pretty chuffed.
I really dont want to have to buy a tablet as well at somepoint.
edit
Oh and fishlabs (i think its them) please make galaxy on fire 2 (or hell make a sequel with less cheese) and stick it on PSM. I will throw my cash at you if you do this. That game with buttons would be awesome (it was still great touch screen only to be fair)
