I'd say get either a Nexus 7/Nexus 10.
But, if you really wanna go Apple, I'd say hold both and decide if the iPad 4/3 is so heavy/big, or if the iPad Mini is so small for a tablet.
For playing in bed, I'd say iPad mini, for school too, as it's way more portable.
The Nexus tablets are way better.
Why? Hardware, software...
Like the Nexus 7 packs a Quad-core where as the iPad mini offer a dual core.
The Nexus 7 offer a HD screen, while the iPad mini has a 1024x768 or so resolution..
The Nexus 10 offers a 2560x1600 resolution display with 300PPI, the iPad 3/4 offers a 2048x1536 with 267PPI or so..
The Nexus devices run Android, which is, better than iOS, trust me.
People will probably say iOS is simpler, but let me leave a Nexus 4/7/10 with my grandmother, 2 days later, she will use it so easily.
TL;DR:
Get a Nexus unless you really want to go with Apple, try both and see which one feels right for you.
