Well, I decided to give PCLinuxOS 2007 Test Release 1 a shot. (I've been running PCLOS 0.93a, the current (previous) release.) Texstar decided to give us a Test Release (often knows as "Release Candidate 1") since the changes between 0.93 and 0.94/2007 were so great.
I had intended to stick with 0.93a until 2007-Final was released, but everything I was reading looked so good. I knew there were some bugs, but I decided to take the plunge, anyway. And I'm glad I did! The live-CD booted up fine, and everything I played with seemed to work okay, so I hit the "Install" button.Now even my poor old system is running Beryl, with 3D effects as good as, or better than, anything found in MS-Vista. I've got cutting-edge versions of my favorite software, and everything "just works". The PCLOS Beautification Project has worked wonders, unifying icons, splashes, and the like with a clean "PCLinuxOS" theme.
I love this system, and the final release can only get better!
