We've now migrated our site to XF 1.2.2 and are using Core but we've had a few reports of the editor becoming very slow/laggy on iOS. I posted on XF about it here: http://xenforo.com/community/threads/editor-laggy-on-ipad.61499/
I've tested this myself and our editor definitely lags quite horribly on an ipad 3 (but seems fine on my iphone 5) but not everyone seems to be reporting the issue so I don't know if you'll be able to reproduce it.
We've customised Core quite a bit (mainly style property changes, colours, etc) so I wanted to rule out it being our customisations. I also thought it was more likely to be our advertising and any slow JS being loaded but after testing things for a while it does seem to be Core itself causing it.
I can reproduce the editor lag on your demo board as well which I think clinches it :-(
I'd be interested if anyone else has experienced similar?
