Cory, Let's keep this on the list in case it is interesting for others. The UW Change group includes several people who have spearheaded an Android toolkit that runs on a mobile device. see http://code.google.com/p/open-data-kit/
As to why the Android OS comes up in "development lists" and conversations... I think that the main reason is that Google has positioned it as the next platform for the smartphone /mobile/ tablet covergence world, Its open, meaning it is being offered to any handset manufacturer and has the backing of major content players in the market (esp Google), plus the backing of major network players. This is a killer combo for market acceptance. This contrasts with the Apple iPhone approach, which is only available from Apple, on Apple handsets, and locked to specific carriers and thus not available in many countries. What this leads to is that the Android marketplace follows a very open approach as well - meaning that applications are created and then made available - there is no process like that used by Apple's to control what gets presented to users. This makes it ideal for small software applications to be built rapidly and launched immediately. We do see Microsoft trying to make up ground in this space, and Blackberry cannot be counted out (largest corporate base of smartphone users), but Android has caught the attention of international NGOs. Both Palm OS and Symbian OS on mobile enabled devices have significant followers and continue to be viable, but both currently lack one of the elements for market acceptance I mentioned above.
