I've watched some videos about Gnome 3 and Unity and didn't like either. So I installed LUbuntu and missed some things. Than I installed XUbuntu and liked it but it also missed some little things. So I installed KDE and liked it but it made my overclocked i7 with 12G of RAM seem slow.
So I gave Unity a try in a virtual machine. Turned out to be not that bad. So I installed it on my overclocked i7 with 12G of RAM... NOW WHEN I MOVE A WINDOW, IT'S TOO SLOW TO FOLLOW THE FRAKING MOUSE CURSOR. I have the latest NVidia drivers, hardware that had never give me any headaches with Linux (Gnome Shell works just fine on the same installation). But Unity makes me feel like I was an owner of a 386 with 4M of RAM.
So what I'm not cool enough to not being able to adapt to Unity. It won't work with my hardware, information on which graphic card I should upgrade to or what I should do to debug the performance problem is nowhere to be found. I don't like Gnome Shell. Turns out I'm working more and more on Windows 7 these days :-(
