I have used my I pad pro daily for almost 3 years now. It's been in countless backpacks, suitcases, etc. I don't have kids, but I'd say it's pretty tough! And I don't have any specific issues with it so far. I have been thinking of buying a Cintiq for the last few months because I want I bigger screen, but honestly the Ipad is so good that I can't really justify buying another tablet... I had a older Cintic before buying my Ipad but sold it because the Ipad was 100X better. I also looked at several knock-off. The one that seems to come the closest to the Wacom is the Kamvas pro 22, but still, it doesn't seem to be in the same league.
Hope this helps!
