That's interesting. I used the SPB shell on a WinMo phone and it was well worth the $30 price. In fact, I wouldn't use a WinMo device without it. On the other hand, I'll be interested to see if it can compete with the absurdly low prices for apps in the android world and whether it provides significant "value added" compared to some of the other home replacements.
It's good to see some of the major developers of business apps taking the plunge into the android market. That's for sure.
