I've been running the previous version (zorin 4...zorin 5 based on ubuntu 11.04 comes out by months end just like mint)...
Just checking it out on live dvd for about 2 days now...actually, it is quite nice...kind of like mint but with more customizations like compiz running by default, and various little "touches" added with effects and the like...it comes with all multimedia codecs installed (like mint) just one panel on bottom...doesn't really look like windows at all (except perhaps for the look of the lower panel and menu).
However, the menu is the GnoMenu and had many options to the look of it...instead of Windows 7 menu look, you can change it to kde kick off style, lancelot menu, and many different "looks"..I even made the lower panel a bit smaller in height by right clicking on it and going to "properties"...
It comes with Google Chrome as the default browser with options for Firefox, Opera, Midori, etc...
And Evolution is the default mail client...very smooth and snappy in performance which i would say is better then the "stock ubuntu" has lots of performance "tweaks" it would seem..Runs very well and this is on a live session not even installed!
Has an excellent control center that is quite similar to mint's where everything can be accessed from...Uses the Ubuntu Software Center of course...And like Mint..they will NOT be going the Unity route! So again, like Mint...it's a MUCH BETTER UBUNTU....
Too bad it isn't more well known...it really is an excellent ubuntu spin off...just doesn't have the name recognition and huge community of Linux Mint....And if you like the "more eye candy" of kde but prefer the simplicity and extra reliability of gnome, zorin really fits the profile for sure...
The default layout, appearance style and customizations give it an excellent look and feel that i find very appealing...
I think they just give it that windows 7 menu and panel look to make it more comfortable to newcomers from windows...but as i said, easy to change and actually, otherwise is really a very linux looking product (not windows at all)...
I'm definitely going to check out zorin 5 when it comes out...may even install it...
