Just throw in my 2c....
At the start of the year, I had my iPad1 on for 9 weeks without switching off... No performance issues.
And, although we don't have a jailbreak for the iPad2 yet, when it arrives there us a lovelly little tweak called NoLockScreen wnich gives you that "instant on" smartcover feel without the cover or magnets. I've had this on my iPad1 for ages... Works great with my Moleskine case.
