After more than a week using an Android-based mobile phone, the T-Mobile G1 from Manila Bulletin and another from a popular electronics manufacturer whose name I cannot reveal due to an NDA, I think I can say that I have sufficient experience to provide you with my impression of the platform.

First, I love Android due to its open source nature and its Linux underpinning as well as its Java development environment. This is actually perfect for a FOSS advocate and a Java Champion like me.  I have tried a mobile phone that runs on Java as well as a mobile device that runs on Linux and I can honestly say that the Android blows them out of the water. Google has done a tremendous job marrying these technology into a single (and still open source) platform.
