It looks as if the new Ubuntu long term support distro will be out soon, with the Mint LTS (17, I think) following at about the end of May. I'm looking forward to the latter. The little of 15 and 16 I've seen suggests that things are getting lighter and quicker. I hope this is the case with 17 - should keep my old machines going a while longer.

A shame Ubuntu whatever and Mint 17 weren't available in time for the end of XP - might have helped get a few more folk out from under the heel of proprietary software.

(I suppose not, really.)
