T-Mobile, Google and HTC just released the new G1 – the first ever really working Android powered mobile device.
I am pretty sure that this will boost the Android development a lot in future. Right after the announcement of G1 Google released the new Android SDK 1.0. After many changes in the past (since the first beta version I tried) this seems to be quite final. There are not that many possibilities for Google anymore to change important programming interfaces within the SDK API. We will see and check out the new capabilities of this soon!
