I dislike intensely the standard layout of the top bar, even with the movement of the Mint Menu up there, the fact you can't move/remove any of the icons, add the ones you actually use etc.
On my M11 top bar I have the Menu, active windows, then the comp-fusion icon, mint update, wally, remmina (vnc client), quit/kill app, and the clock thats it. All the rest live on my avant dock that's the way I like it. I don't need to see the network/volume/etc all the time & I don't use any chat clients so don't want them on the screen.
I expect that'll come in time; the crticism G3 is getting now (as far as user-configurability goes) is reminiscent of that which early G2 releases got.
I have spent several years getting this setup like I like it, now I am being forced to change it, NO! I could stay with M11 but newer releases will want updated libs that won’t be available so forcing me to move to a newer one.
I believe CentOS 6 (with G2) will be supported until 2017; I guess it comes down to whether the version of the apps you use is more important that your desktop environment......
Since Mint is the only one that seems to work for me (I tried Suse didn't even get a screeen!, don't like KDE any more - I started on Linux with Mandriva using KDE, back in the 90's) I have lxde on my eee with a very minimalist setup - openbox wm - but that is a bit too minimal more my main pc.
A friend of mine is a long-term SuSE user; gives me a LiveCDeach time a new release comes out and encourages me to try it - I tried the latest (12.1) yesterday. Worked as well as any other LiveCD I've tried - KDE 4.7 looks very slick (KDE 3.x never did much for me) - I'm sure it'll be just as slick on my MacBook when it's made its way into the Debian repos. I have LMDE/Xfce on a netbook; once t's set up the way I like it, I'd be just as happy with it on a desktop.
