Documents being used in the Apple v Samsung courtroom clash of 2014 have revealed that Google's mobile OS was, as previously mentioned, heavily leaning towards a Windows Mobile-esque keypad input rather than the swizzy touchscreens that it ended up with.
The 2006 document, which refers to Android as "the Product", says, "Touch screens will not be supported. The product was designed with the presence of discrete physical buttons as an assumption. However, there is nothing fundamental in the Product's architecture that prevents the support of touchscreens in the future."
As such, the 2006 version (0.91) required a host of keys - a minimum of "Numeric, Star, Pound, Send, End, Home Back, 2 Soft Keys, 5-way navigation (up down left right select)."
The basic design was that of Google's original 'Sooner' device, which was in essence a cross between Symbian and BlackBerry with a swirl of Windows Phone thrown into the mix.
Change of plan
This one had a whole section dedicated to the touchscreen, which backed multitouch and dismissed the stylus.
The first Android phone, the HTC Dream / T-Mobile G1, was released with a touchscreen (albeit also with a slide-out keyboard) in 2008 and the rest, as they say, is patent-warfare history.
