Okay, I kinda disagree with *both* [Jorge's answer](http://meta.askubuntu.com/a/5683/2355) and [gertvdijk's answer](http://meta.askubuntu.com/a/5684/2355) to this question.

[tag:mobile] is not exactly "overly broad" - of course it also includes [tag:ubuntu-for-phones] and of course a great ton of stuff fits into it, but it was made with the "running (actual) Ubuntu on mobile devices" idea in mind.

[tag:ubuntu-for-phones] on the other hand is, for the most part, focused on the phone derivate of ubuntu - which certainly provides a wholly different UX.

**These two should, in my opinion, be kept apart.**

However, since [tag:mobile] does include [tag:ubuntu-for-phones], perhaps renaming the previous [tag:mobile] to something more distinct - "mobile-ubuntu", "mobile-installation", something like that - might be in order.
