Wow i just read a news about a smartphone device made by Canonical(UK). It is able to dual-boot Ubuntu mobileOS and/or Android. As soon as you plug it on to a external display+mouse+keyboard it's running the 100% Ubuntu desktop operating system.
Seems pretty cool. Sadly it is a crowsfunding project
