I know some of you are already using Android devices to be productive today. And, I know a lot of you are using them to compliment a standard setup instead of replacing it. But, if

Consider this the series kick-off and I'll check back in periodically to let you know how things are going, and then supply a full summation at the end.

In the meantime, what's your experiences?
