Good device that doesn't cost a pretty penny?
HUM!
You could:
- Use any pre-existing phone and a game controller to go with it
- You could get any of the existing Chinese Android gaming phones/tablets/phablets with built-in controls
- You could buy an *shudders* iPhone and a nice controller to go with it
Now, techically, as of today
(bare with me now), iOS does have better exclusives and does get better
"big name developer"support, however the scales are gradually tipping towards Android's favor with the increasing marketshare. The problem with Android is that it has an Open Source policy and as such, game developers are sometimes afraid to release their games for it... which doesn't stop the great majority of them from hitting both platforms.
The handful of iOS exclusivels is easily outweighed by the fact that Android is
(usually) easy to ROOT, easy to install any Apps on and has an extensive variety of emulators in its store, most are free, too! The iOS store does not allow emulators on-board, so you're practically
required to Jailbreak which is a b*tch each time a new iOS revision is released.
Not only that, Android has the specs advantage
and it's cheaper - more bang for the buck.
Once you decide which side you lean towards the most, we'll talk specs and price range.
