Re: iPad Mini 2 - The screen on the current Mini is awful...
I agree about its poor specs (I suspect a lot of people buying it think they're getting the specs of a full price/size ipad for "less" money - Samsung have done a similar trick with the S3/S4 Mini phones, which are actually lower spec, with many people not realising). Though just to comment on:
"as well as proper tablet versions of apps"
But what's a proper "tablet" version? It's more a question of devices of different sizes, but the problem is now that all of the IOS apps for "tablets" were designed for a 10" tablet, so it's wrong to assume that they magically work on an 8" device as well too. I mean, why does a 10"-designed UI work fine on 8", but a 5"-designed UI not work well on 7"?
Android has been designed to work with a range of four different sizes, with developers aware of there being hundreds of devices, for years. Whilst a model of "specifically design for one or two models" can work better, it blows up when they they try to generalise that to having more different models.
