Have you jailbroken your iPad? I have had it for months and I don't know that I can recall one time that I had to reboot it.
Ironically, my Droid Incredible has been running MUCH better since rooting it. Funny how it works.
Nope, no jailbreak here. yet. I didnt reboot much either at first. I'm sure its an issue with one or more of the apps I have installed, but that's the point. Like every other phone platform out there, apps can decrease performance and stability of they arent coded right. The app store and approval standards help some, but they are far from a guarantee that everything will "just work".
I also only get 6-7 hrs battery life now. This is still completely acceptable for my usage, but I'm tempted to start removing apps one by one to see what the problem is.
