Does anyone know how hardly it impacts battery life in comparison to gnome?
not sure about gnome or even actual battery life, but when upgrading from kde 3.x to 4.x I noticed that my laptop got significantly hotter. I'd guess it was due to compositing and animating everything, resulting in higher GPU frequencies.
Disabling compositing or switching to the lightweight XRender based mode might have helped. No idea, I went back to 3.x because 4.2 failed every time I attached an external projector. I'll have to try 4.4 again soon.
I'm not big into the whole KDE vs GNOME fanboy nonsense, but I think it's more than fair to compare them from a technical standpoint. The biggest selling point of Gnome 3 was gnome shell. Well now we have a problem:
If you look at the videos, almost everything Gnome 3 promised is already implemented with the updates to Plasma. All fanboy BS aside, Gnome is yet again lagging behind KDE in terms of features and functionality. As usual, Gnome is saying they're going to implement something, while KDE is too busy actually producing.
