I have app box pro app where I can check system resources being used. I noticed my iPad would not even load the app store. My webpages were just blank and would not load I opened up app box pro and it showed 92% RAM being used. Obviously the easiest solution was for me to clear all my cache, cookies and history in safari, close my 4 web browser windows and also reboot iPad. After rebooting I opened app box pro and system ram only showed 40% being used. So iPad was back to being fast again. Like many, wished apple would have shipped with 512mb of ram. I hope with iPhone os 4 gives us the option not only to close multiple apps but I hope we are able to close "native apple running apps" like calendar, iTunes mail so I can free up more ram. Still love my 3G iPad. It's web browsing is very fast. I just hope I don't have to reboot my iPad more than once a day to free system ram.
