I have an ipad 3 running ios 7.1.2. I initially avoided downloading ios8 after reports of poor performance on the ipad 3. But there are many apps (some that I had already purchased) that now require 8, which is tempting me to switch over. Is it worth it? I have not experienced any problems with my ipad running ios7, but after hearing stories of a drop in performance with 8, I still worry how my device will respond to 8.4.1. Has anyone else experienced issues/hangups with the upgrade?
