OK, how many of you out there are interested in running Windows 7 on an iPad?
If you're interested, then the folks at Citrix are working on a solution for you. Sure, it's aimed at enterprise users that currently use XenDesktop or XenApp, but it opens up the possibility of using that iPad as a Citrix receiver and get Windows 7 piped directly to the tablet. The iPad's 9.7-inch screen makes a capable 1024x768 monitor.
I like this, if for nothing else than the ability to run an OS that lets you multitask on the iPad.
