The Google Sooner, aka the HTC EXCA 300 was built a year before Android was officially released. It is supposedly the device that Android was originally built on back in 2007. It had a hardware QWERTY keyboard and non-touch display. It was clearly modelled after the most successful smartphones of the time – BlackBerry and Nokia’s E-series.
There are speculations that Google had to go back to the drawing board when the first iPhone was announced. Supposedly, because of the iPhone, Google added a touch interface and other features. There is some debate over the specifics. What do you think?
