I purchased and for the most part enjoy using my T-Mobile G1 Google Android device. According to Engadget it looks like the second Google Android device may be coming soon to Australia from Agora. Ruslan Kogan posted more details on his blog about the Agora and Agora Pro.
These two devices have a BlackBerry form factor with an integrated front-facing QWERTY keyboard. Specifications include a 320x240 2.5 inch touchscreen display, Bluetooth 2.0, and microSD card slot. The Pro version also adds GPS, WiFi, and a 2 megapixel camera. The prices look incredible at US$192 and US$256, with availability scheduled for 29 January 2009. Specifications show it has support for the 850 MHz UMTS/HSDPA band so it should work with AT&T's 3G network. If not, they have quad-band GSM so it will work with AT&T and T-Mobile. I ordered one and will post a review as soon as it arrives.
