I have seen people walking around playing pokemon go on ipads before (when i was playing) so i think it should work with her ipad, if it doesnt then im sorry but atleast you still have an ipad!
I once had not knew about these cores, but now i know a fair amount after reading these replies. helps me out a bunch as i soon hope to make my own computer :3
Personally i think it looks good, but then again im also a bit of a noob at this sort of stuff. Good luck with your options and i hope it turns out to be the awesome computer you wanted!
