I figured I'd post this as some users are unaware of some of the enhancements Gnome 3.14 has brought to the table. Gnome 3.14 now has support for touch screen devices and as such users could possibly benefit from this with the recent launch of SteamOS.
For those who are questioning the addition of this, here it is from the source itself:
Oh we know. It's Just NOT every Distro has Support for it, Personally though All Distros need to support it. Most General Use Laptops now-a-Days come with a Touch-screen. it would be nice if your favorite distros support touch-screens.
Support has been implemented in the kernel since 3.8, but Gnome 3.14 seems to be the first real implementation from a DE that offers it apart from simply single-touch experience, i.e. before Gnome 3.14 and most every other DE in existence (and most not very well implemented anyways).
Having used/tested Gnome 3.14, I think the multi-touch experience has come a long way, and I appreciate that as a convertible laptop user. The keyboard still sucks (Gnome: upgrades DE to multi-touch, doesn't change the on-screen keyboard) and has a couple of usability features. Still; it's getting better. In fact, I like Gnome 3's design for convertibles much more than Windows, and it's mostly a cohesive experience too. I'll look at it again when 3.14 comes to Arch or the next version comes out.
Linux has had touch support for years. Gnome Shell also. What Gnome 3.14 does is merely offering next gen multi touch GUI navigation. KDE plasma active 5 should be better though for some users. There are also other multi touch GUI featuring DEs in Linux, Android is the most popular, but there is also Unity 8 on Mir available now in Ubuntu 14.10.
Who knows, there is absolutely no application or system support for mir, the only thing that uses Mir is Unity 8, and that's still in a very early phase, because it only has a few apps available. All the other apps you run, run in X.
This is not such a big deal, after all, the same can be said for most applications for home users in Wayland. Wayland has pretty good support for pro stuff, but for home users, it's pretty much zero.
Unity 8 doesn't seem that bad, but it's not original, it's basically Gnome with a static and featureless copy of the KDE plasma active activity bar, which works like the Windows 8 metro screen... but some people may like it, it kinda works OK, and it's free... so there really is nothing to complain about imo. It's just not Wayland, because it's not supported by anyone but Canonical... even the community Ubuntu remixes, like Kubuntu, Lubuntu, Ubuntu Gnome and Xubuntu, have already confirmed that they will not be supporting mir... but hey, that's what open source is for, maybe Canonical is right, and mir will be the greatest thing ever since the invention of ice cream, who knows...
