I am conflicted, I don't know if I should update my retina mini to ios 8 or not. I use my ipad mainly for games and I just read on a blog that Metal is not available on ios 7. Custom keyboards, widgets, Metal, all these make me update my ipad but my lag OCD really pushes me back. I can't bare any lag but there are some lags in ios 7 that have been fixed in ios 8 and some ios 8 lags that aren't in ios 7. Also, how do the Apple apps like imovie, pages and other work on ios 8, are they laggy? Is anyone regretting updating to ios 8?
