They just keep coming, like zombies, wave after wave. Another day - another new Android device sees a day light. In fact, there have been days, when actually a bunch of new Android devices have been either leaked to publicity or officially released. Not just mobile phones, but more interestingly a variety of device types including e-book readers, multimedia players, mini laptops, and MIDs. Google's CEO Eric Schmidt predicted that "Android adaptation is about to explode", and that is exactly what is going on right now.
You can check (an almost :)) complete list of Android phones from Techcrunch'es web page: "Android Avalanche". In addition to those officially released Android phones, there are lot of leaked phones published on Internet. Just today, one of most interesting ones, Dell Strike was leaked on a Vietnamese web site. This beast is running Android 2.0, and boasts both 3G and Wi-Fi connectivity, huge 5 inch WVGA multitouch capacitive display. A 5 megapixel camera is backed up with dual-LED flash.
Competition is good. I think the fierce competition among Android device manufactures will result as a rapid evolution of Android devices, as well as fuel innovation of Android related UIs, applications, and services.
