Hi Doktor!
It's not bad, especially if you consider that it's a very new DE. Although KDE 4.80 is now really fast (faster than former versions on my machine), RazorQt feels snappier. Everything is a little bit faster. Except the right-click context menue on the desktop, there is a one second lag. Also startup is really fast. LXDE is a little snappier and faster than RazorQT, but only the tiniest little bit ...
cheers,
Bernd
Edit:
For parts of the configuration, you need to edit config files - which works good. USB-drives are mounted immediately - like in LXDE. Development and improvement goes on, as one can see at the google-group.
I like RazorQt, and I will use it as my main DE in the following weeks ...
Edit 2:
I tried RazorQT with Openbox (which is standard). But you can also use Kwin (you've never seen such a fast Kwin ...
) or Metacity ...
Now after my words of profound wisdom, I'm going back to procrastinating.
