As you may know, the LTS versions of Ubuntu receive point releases which bring both security and kernel updates. Most of the time, Canonical respects its own timeline, except the cases when there is an important matter which are worth the delay.
This is the case with Ubuntu 14.04.2, which has been delayed with 2 weeks, from the 4th of February to the 19th of February.
The mobile market is saturated. Any new entrants are doomed from the start. And if you need proof, just look at Windows Phone or BlackBerry. The problem is that you need an app ecosystem to gain market share, but you need market share in order to entice developers to your platform.
There are so many Linux distributions, each one claiming that they are the one flavor best designed for the new user in mind. Ubuntu, Linux Mint, PCLinuxOS -- all outstanding distributions and very much ready for users who want a platform built on the premise that Linux isn't nearly as challenging as many people assume.
In 2014, a new distribution appeared out of nowhere, one that cut straight to the heart of the matter and promised to deliver a Linux distribution like no other. That distribution is Evolve OS. For the longest time, the distribution was in a state of limbo, and the best you could do was download an alpha and hoped it would run. I tried a number of times and finally opted to just install the Budgie desktop on a Ubuntu distribution. That attempt gave me an idea of how Evolve OS would look, but not much more.
For those that haven't yet tried out recent builds of Ubuntu 15.04, it's very easy to try out systemd and switch between that and Upstart. On Ubuntu 14.10 it was possible to experiment with systemd by installing its packages but now with the Vivid Vervet it's installed by default. Until making the default switch, Ubuntu 15.04's GRUB2 configuration has a kernel option for the stock boot parameters (using Upstart) and then an alternative one using systemd. So from GRUB2's menu you can simply switch between Upstart and systemd. The systemd option just appends init=/lib/systemd/systemd to the kernel command-line.
