Effective immediately, the new release of Ubuntu, 17.10, aka 'Artful Aardvark' has been released!
This release will be supported for 9 months (until 2018) for Long Term Support, stick with release 16.04, instead.
Official flavors (e.g. Kubuntu) are also released.
See the above release notes for a full list of changes and where you can get a copy.
[Full disclosure: the majority of SoylentNews' servers run Ubuntu 16.04 LTS though we have taken steps towards moving to Gentoo.]
The customized version of GNOME that Ubuntu 17.10 uses is very much in the mould of the (now defunct) Unity desktop, so it won't be to everyone's tastes.
damn. go to macOS if you don't like extra control on a mouse (I can never use those dumbed down macs).
Gnome3 seems to really appeal a lot to people who love Macs or are admirers of them. The mindset is exactly the same: "you will use *this* workflow that we have decided is best for you, and you will not deviate from it, because we developers know better about how you should use your computer than you do." Except I think even Macs have a little more configurability than Gnome3. Gnome3 users like being condescended to.
windows also seems to not want to use a middle mouse button.
For copy and paste, no, that's purely a Unix/X11-ism. However, many applications in Windows happily use the middle button. Firefox, for one, lets me open links in new tabs right out-of-the-box with the middle button in Windows (not sure about Chrome, but I think so).
