Feeding and playing is great on a tablet with a stylus :) I do that during lectures a lot, it's much easier than clicking and scrolling with a mouse, imo.
Digging is best with a keyboard though, since enter button ^^ But luckily my surface is good at both, I just need to click on the keyboard for digging. Seriously, that thing is the perfect KofK device :D (Aaand for studying, which I got it for, for much the same reasons - great mix of usable as digital paper but also able to run stuff and code on. I love this thing.)
I don't like feeding and digging on my phone either. Doable, but unpleasant. I also don't like to do longer posts on it, which sometimes leads to me reading something, thinking of a long reply and never writing it, because I think "I'll write it down at home" and then forget all about it
