The first thing you need to know is that Ubuntu 14.10 is almost exactly like 14.04. There are virtually no visible meaningful differences as far as I can tell. So if you are using Ubuntu and are sticking with Ubuntu, don’t expect pretty fireworks. This will not be an exciting upgrade.
Second, 14.10 has an updated version of the kernel, the deep guts of the operating system, and this is important. It is good to have a current kernel. Also, this kernel has some important new hardware support. Some Dell laptops have the ability to turn off your hard drive if it feels itself falling, so the drive is not running when your laptop hits the ground. The new kernel actually supports this feature so if you have a newer Dell laptop, you might want that. There is some improvement in the handling of Dell touchpads as well. The point is, you should absolutely upgrade to 14.10 for a number of unexciting but still potentially important reasons.
It didn’t happen overnight, but Steam’s catalogue of Linux games has grown significantly over the last few years, no doubt helped by the release Value’s Debian-powered SteamOS. Abandoning Windows for the open source platform was once the quickest way to gaming frustration, be it a lack of native ports or wrestling with the likes of Wine or other virtualisation option, but with almost 700 working titles available, the variety is certainly there.
Back in July 2013, Canonical proposed a new type of smartphone, an extremely powerful device that would be built with the best the industry had to offer at that point. It's safe to say that it attracted a lot of attention and that people keep wondering if there still is a chance to see something like it.
The crowdfunding campaign aimed to raise $32 million (€25.3 million), but it fell short and only managed to gather $12.8 million (€10 million). Even with less than half of what it needed for this project to succeed, Ubuntu Edge still remains one of the most successful crowdfunding campaigns.
Canonical made a very good release back in April. Ubuntu 14.04 LTS was very well received and it integrated many features. It was very different from Ubuntu 13.10, so it was spared the "boring" rhetoric. On the other hand, Ubuntu 14.10 will not bring any important visible changes to the operating system and it will be very difficult to set it apart from Ubuntu 14.04 LTS.
Many users will be tempted to think that nothing has changed, but an operating system is complex and it has many components that are not visible to the regular users and that can contribute a great deal to the overall performance of the OS.
