Greetings.
I just discovered Pinguy OS last week. I tried it out for a couple of days on a spare computer and was very impressed. So I installed it on that computer, and last night I installed it on our main desktop computer. So far I LOVE it!
I'd been having numerous quirky little problems with Linux Mint (which I also love, and have used for about a year and a half), like printer and scanner stopped working, could no longer auto-mount USB sticks, and a few other weird things. Everything 'just works' with Pinguy OS, and it's surprizingly quick and graphically beautiful. It's a nice blend of Ubuntu, Mint and OSX. And most of the pre-installed apps are ones I use. Nice job!
Good luck.
