Let the hive mind of Engadget get that for you.
"With all the new multitouch capable monitors coming out, which one is the best? With the release of Windows 7 I really want a touchscreen monitor for my desktop. I'm looking to get a Full HD monitor that supports multitouch and can still look great during gaming and movies. Which one has the best specs for the price?"
Seriously I'd sooner let someone star using a hacked Nintendo DS as a phone then allow a damn iPhone in our environment. If someone wants an iPhone more power to him/her. You ain't linking that shit to our hardware beech. Apple is only moderately consumer friendly. Their practices are outright hostile to the enterprise and it will be a cold day in hell when we start using their shit for business.
