I think if it was just sitting in your office on a dock, you really didn't need it in the first place. iPad was designed to use in a variety of situations, most of them involving portability. I use mine a lot on the train to and from work, or when I want to get something done, but keep an eye on my kids at the same time. It's a great e-reader, great gaming machine, great bedside TV.
One thing I would NOT do with it is stick it on a dock and keep it in my office.
Using an iPad on the train in Boston with an iPhone 4S in my pocket would look slightly obnoxious and would probably attact the attention of young crooks looking for a snatch and grab.
