I love how you're sending this from a tablet anyway, you're looking for a replacement?
I'm going to be honest with you, but remember this is my opinion so someone else ma think otherwise... The iPad is one of the most user friendly and easy to use tablets on the market, going from that to something like an Android tablet will be a big jump. I'm not saying Android tablets are rubbish, but in terms of usability I think they have a long way to come.
A Windows tablet might be worth a go too, especially with Windows 10 coming out, should be very interesting, plus it'll integrate with your other Windows devices a bit better (and your XBOX One if you have one)
