Re: HTC One Question / Running on Ubuntu Laptop
It depends what you mean by "syncing". If you mean "copying address book and SMSes to the computer", then this functionality might be hit-or-miss on Ubuntu.
If you mean "backing up my address book", the phone itself will back up your contacts to Google's server.
If you mean "putting music/photos/videos onto my phone", you can access the phone's storage on Ubuntu 13.04 and above as though it was a flash drive. Music and video files placed on the phone in this way will be playable on the phone.
Everything else, such as installing apps and doing system upgrades, are done entirely in-phone and don't require a computer at all.
I try to treat the cause, not the symptom. I avoid the terminal in instructions, unless it's easier or necessary. My instructions will work within the Ubuntu system, instead of breaking or subverting it. Those are the three guarantees to the helpee.
