One of the big differences between Ubuntu phone and Android, iOS and other mobile operating systems is that it's designed to work like a desktop OS when connected to a big screen. Instead of mirroring the screen when you plug in an HDMI cable, you'll dock your phone with a monitor, keyboard and mouse and get a mouse pointer so you can use the OS like Ubuntu on a PC or laptop.
According the Shuttleworth, this makes Ubuntu phone a proper personal computer where Android is not. He also said Ubuntu phone wasn't aimed at iPhone users, who have an "emotional connection" with the ecosystem.
