I'd have said get an iphone/ipad myself but since ios6 the app store has been pretty much unusable.
Ermmmmm. Get a Nokia 3210 and a Sega Game Gear instead.
I'd be interested to know in what way it is unusable? I'm stuck on iOS 5 on a first gen iPad so cant test, but was planning on getting an iPhone 5 as a result of Google pissing around and this could sway me to WP8. I've not heard anyone else have issues with the store either.
As for a VPN, I could with ease but why the hell should I? I want my tech to work, not to have to dick around bypassing arbitrary restrictions. The Amazon appstore might not be restricted but the app selection last time I used it was dire in comparison to the proper one, and the store its self was barely functional.
