Hello! First time here, and still fairly new to iPads and other iStuff. I'm a computer science/information security instructor who has been a full-time geek (student then professional) since 1975 but still very little experience (or rather, all basic user-level experience) in the Apple side of things. For personal use, I have an iPad 1, iPod Touch 4, and I'm still trying to decide whether to get an iPhone 4S or wait until 5. For work I just received an iPad 2 via a grant, which I plan to use in my Information Security classes in three ways: To store and manage course materials (and I'm starting to scour iTunes U for related stuff), to demonstrate to students how to secure mobile devices, and to test students' network security with regard to mobile devices.
