Kwin for my desktop. Really like it. But for my old laptop, I installed Bodhi and find that Bodhi/e17 to be an excellent performer on low-spec computers.

Enlightenment

I had good time with Openbox on Mint-9. So voting for it.
Enlightenment could get my vote, but I found Openbox could be more easily customized than E17, so....

Regards.

Compiz is good one.

Openbox!

Started using it with CrunchBang back when the new "Light" design/re-design/re-branding of Ubuntu was released (10.04 LTS IIRC), but had been wanting to try *box for years before that but never got around to it. Minimalistic. I love it.

Voted fluxbox because its my favorite, but this year had a lot of great window managers get more popular. AwesomeWM got a lot of attention in the tiling window managers, but Openbox certainly got a lot of attention this year thanks in part to Crunchbang and Arch becoming more popular, and a Enlightenment got even more after Bodhi came out of nowhere and turned a little window manager into something that the end user can enjoy.

Right on OpenBox. I recall not so many years ago when OB would be in the single digits. Now it's the winner! That says much, methinks!!

Wow…close tie between Compiz and Openbox…just one vote!

I have been looking more closely at e17 as of late and would have voted thusly, as it is getting the nod for my next workstation build.

Wow, Openbox won. It is a great little WM and probably thanks to LXDE for using it as default WM. I always have it installed on my systems.

I would think that it is the other way around, LXDE uses Openbox because it is a great WM.

Heh! The year of the Boxen!
Well done, guys...

My favourite *box is Fluxbox - once I'd worked out how to do all that low-overhead bling by tweaking text files it was a gas to use. Boxen are good value, one and all.

Like MrRtd, cowlitzron, savotije and gotfw amongst many others I'm also getting great results with Enlightenment, which is fulfilling its promise with all that development paying off last year - the EFLs are not just Beta, but full release status now. I checked for flying pigs, but could only see angry avians....
Bodhi Linux has been an excellent, stable showcase for E17's cpabilities - this Laptop has Bodhi 1.3.0 running on a 1.6 Celeron/Intel graphics and it responds snappily with the bling turned on, and matches 'buntu LTS stability.

Did you see that there is a Bodhi respin with a 'full fat' set of apps pre-installed? And it's called Bloathi!
No, it's not slow or sluggish, the name is intended humorously. But it does have a good selection of apps on it, and makes a very useful USB-stick installation. More on it here.

Compiz always.

Srry, didn't vote this yr.. Next yr I will vote xmonad... Like the tiling windows manager better then compiz.. It will get my vote. ... Enlightment have to give it another college swing

Xmonad takes me back a couple of years! Glad it's still going.
Haskell is strangely powerful, isn't it?

Recently I've only played with Tiling desktops (for a bit) in Enlightenment, but I find I'm now pretty well wedded to the more conventional metaphor together with virtual desktops. Find myself helpless with frustration on (eg) a friends Vista machine that needed surgical attention.
People get set in their ways, and my first experience of GUIs was DR GEM in the early '80s. Pretty good GUI, GEM.
It certainly helped to have GEM on early Win machines, since it had far better file management - and it would indeed run under (employer mandated) Windows if you had enough RAM.
Did use a tiling option in one early Win environment - it was most useful in a coding/CAD context iirc.
But by then I had probably become acclimated to the other method.
