well im pretty sure RH!!Enterprise!! linux customers will have the proper supported and !!Certified!! hardware for RHEL7 when they decide to upgrade and the same will happen with the !!Enterprise!! software that will be used on those workstations.
taking the fact that 99% of RH customer use Firegl and Quadro class hardware a composited desktop won't be a problem at all since both are well supported in RH.
now if you don't like composited desktops you can always choose another DE with fedora or any other distro
Gnome 2 wasn't broken and didn't need fixing. Perhaps the Gnome devs should have been more mature about how the handled the situation. As it stands I have no support for them just as KDE lost me with KDE4, even though their moronic "force everything to have the letter K shoehorned into it" based naming scheme never totally won me over.
Mate is doing it the right way, using the long proven good desktop and adding in only the bits of Gnome3 that are actual improvements over what already exists in Gnome2 instead of trying to reinvent the wheel after downing 2 liters of vodka and beating your self in the head with a hammer for a week.
It's like saying that having a few million distros is somehow progress, newsflash, it isn't because there is so much duplication of effort that it kills any chance of innovation.
There's not a fixed amount of development effort that will get split among a variable number of distros. There are people and corporations that want to do certain things, and they do them however they want. A lot of people split off because the folks they'd ideally like to work with have incompatible goals, stricter or less strict quality controls, or they just can't get along. If we banned every distro except Debian and every DE except Gnome, that wouldn't mean that all the work Clem has done on Cinnamon would be in Gnome instead. It probably would mean that Gnome would have rejected his submissions and he would have gotten frustrated and stopped developing.It's like saying that having a few million distros is somehow progress, newsflash, it isn't because there is so much duplication of effort that it kills any chance of innovation.
