Nvidia have just relaunched the Shield K1 Tablet for £150 or $199. It's an Android 8" tablet which will run Aerofly on maximum settings, so should be good for update longevity despite being effectively already over 1yr old.
I've just picked one up exclusively for Aerofly.
Do you think a smaller tablet will inhibit the experience compared to the likes of the full size ones ie. iPad Air?
