When I first updated to iOS 5 I thought it was great. Now not do much unless you have a iDevice with more than 256 mb of ram. Even with a new iPod touch apps crash that use to never crash with iOS 4.3. I knew that the current touch had limited ram I upgraded for the Retina display I check the logs and just about everyday it says low memory. If you have a iDevice with 512 mb of ram then you are fine. Why did Apple bother releasing iOS 5 when it sucks up so much ram?
