The Verizon VZMinutes widget shows off the best reason for using the Dashboard. Its just a shame that widgets in general take up between five to 10 MB of RAM each. Some people are spoiled with RAM though.
In short, Widgets are Sherlock without all the overhead. Search engine widgets are great, RSS widgets are nice, comic widgets are fun, but these web services widgets like the VZMinutes widget are the reason Dashboard really shines.
They work mainly because, in this case, I hate going to the Verizon Wireless web site and login every time I want to check my minutes.
Of course I would not store my PIN on any computer other then my own, for obvious security reasons.
I should note that this is in beta, and it very much acts like it. It does work though, just not all the time.
