I really like intelliscreen, and after a few updates was ready to buy a license. What I have noticed however, is a conflict with the iphone digitizer (touch screen) and intelliscreen at initialization.
Over time, the iphone digitizer would respond slower and slower and at one point, would not respond unless I restart.
I turned off intelliscreen and ‘ta da’ the OS and digitizer is snappy again. I think I will go without this app for awhile to see if the system keeps running well. I will try again though, perhaps on the next update of the application.

BTW, get QuickGold. Not perfect, I did miss an address while testing, but still. Great. A must have.
