As a member of the Open Handset Alliance, HTC's move is unsurprising. The HTC Dream -- known by most as the G1 -- was their first success. The phone debuted Android for the world, demonstrating the platform's flexibility. HTC will capitalize on this growing market with their "flagship" phone for 2010, the Bravo, which will be an Android device.
Android 2.0's feature richness may have been a factor in HTC's decision. If it can pull a company away from Windows Mobile 6.5, it could erode market share for other big-name players too.
