iPad for me. I'm just using my mom's old iPad 3 for sheet music and that's the only time it's used.
I've tried a bunch of tablets (iPad 1st gen, 3rd gen, mini, mini 2, HP Touchpad, Surface Pro 1, Surface Pro 3, Dell Venue 8 Pro) and ended up returning or selling them lol.
If I need a bigger screen than my phone, I'd rather use my macbook pro or desktop.
I don't have as much free time as I used to so my vita, ps4, wii u are collecting dust. Have so many games to play too *cries*
