Well besides the obvious reason that all the cool DBAs have iPads.

I guess the best way an iPad could help me do my job is the small, lightweight, and overall portability of the device. I work for a small company and we don't have a lot of DBAs, ok only one. Having the ability to troubleshoot and monitor remotely without having to lug around a clunky laptop would be a great improvement. Plus being able to do in-flight monitoring and diagnostics via accessing SQL Monitor on the iPad would be great when I am on Wi-Fi flights traveling. Digging out my laptop from my carry-on can be a pain. Assuming that it will work from the top of Mt Hood it would be a great Christmas present that allowed me to go snowboarding with less worry about being called in to work!
