Ubuntu Touch on my Nexus 4 is the only mobile OS I use. The interface takes getting used to and is beautiful. I also like the fact that it over heats so much that, when rested in my jacket pocket, it keeps my left nipple nice and warm.

Seriously though, each week it seems to get better, and there's nothing like having apt-get on your phone. Hopefully Touch will be a success and help introduce more people to Linux. (I know Android is Linux but it doesn't feel like Linux)

Jailbroken iPhone users and N900 users would definitely agree that apt-get is a must have if you're a dev/geek.

I haven’t tried it, but there is generally no need for interfaces to be intuitive, as long as we use these interfaces in the long term. On the contrary, it is often preferable to have a less intuitive but more powerful interface which lets you get your stuff done quickly rather than an intuitive interface that forces you to spend longer on trivial tasks; especially if the ‘interface’ in question is the phone you use daily for 2+ years.

Of course, this implies that Ubuntu for phones actually lets you get stuff done quickly (after a while of getting used to it), rather than being unintuitive and useless.

I can use it, my wife hasn't a clue. For the first time in my married life I have text message and email privacy.

Could she use it if she spent an hour reading the manual? (Is there a manual?)

Probably, but she's an iPhone user and as such has no understanding that there might be a manual for a mobile phone. It either 'just works' or it doesn't.

Ubuntu Touch on my Nexus 4 here. As a previous user said, takes a bit of getting used to, but it is the only thing I use now. I still have an old Galaxy Nexus with Android lying around, but it hasn't been turned on in weeks. I'll probably flash that to Ubuntu Touch as well and give that to the wife.
