I do not do upgrades until I feel that all the issues are behind us. I am not technically good enough to deal with problems and figure out how to fix them. I recently upgraded to the 6.1.3 and I am pretty sure my iPad operates at a slower speed. I have an iPad2. There is no way for me to put a stopwatch on it but I use it a lot and am quite sure this upgrade slowed my machine down. Has anybody else experienced this and also what can I do?? Many Thanks.
