> In September 2008, the first Android phone went on sale—the HTC Dream,

Excursion: HTC would later sell the HTC HD2 with WindowsMobile (a predecessor of WindowsPhone), which could be "dual-booted" with Android ROMs from the XDA-developers forum or similar.

The 2009 HTC HD2 was basically the modern glass slab, except for a discrete bottom line of physical buttons, which hadn't yet been eaten by software at the time.
