Case in Point: Touchdown's Exchange solution is a great little Mail/Calender/Taks/Contacts app for Android that better serves my needs than the default apps.
I can move it to any android phone on any carrier.
Should you get an Android netbook in the future, it is more than likely you can use the app on that platform as well.
Currently, the only other platform than can offer consistency between carriers (that is device manufacturing agnostic) is Windows Mobile.
Pretty weak reasons, IMO. And I'd say that any product so general it can run anywhere is also mediocre at everything.
