iPads are great, they don't crash as much as the android devices (from what I read on here, it's mostly Android devices that crash) they are fast and non-laggy. But they are dearer (only on the day you buy!) and they suffer from screen glare. I fixed this on mine by buying a tech armour screen protector for about £7. Works well - and you get two! You hear folks saying that iOS devices have the simulator option, but TBH, it's pretty crap.
