Interesting... I'm currently mulling my options for my upgrade due in March. I have a basic phone now, so I'm not locked into any ecosystem. I have always admired Ubuntu... and their demo of docking the phone and turning it into a PC is impressive. Not sure if it beats an S3/4 or an iPhone... but worth investigating.
Do you know anything about it? (Or can anyone else chime in with their 2 cents?
)
