You're right in theory but my ipad2 was crashing so bad due to low memory it became almost impossible to use. The logs proved it. It started with 5.0. 5.1 helped a bit but didn't fully stop the crashes. I did get a new iPad and am very thankful for the increased ram?You'll get this on any iOS device because of the way the OS works. It keeps the RAM loaded with recent app data in case you were to swap back, and only dumps it when the RAM is needed for something else. So it will report low memory, which is technically true, but it doesn't matter in the scheme of things because it knows what it's doing with the management.
