Old devices iPad 2 and iPod Touch 5 - after iOS 8 upgrade experience report!

I will be home a week ago, two of the oldest device upgrade iOS 8 had to say when the machine will not give it a try, the result was better than expected. iPod Touch did not upgrade any problems after 5, iPad 2, there is often little crash, but I cleared away some useless App after completely like normal with the same! Even faster than before (perhaps illusion). So if someone feels slow, it is likely that a relationship with insufficient space. I recommend you stay in the iOS device at least 1GB of space, so less likely to have a crash situation.
