linuxpcplus not bleeding edge, period.
Highly stable, that (and the excellent forum) is what keeps me here. I know some are enjoying the 64 bit version and say "look at me, it's stable" but it has not being released so I guess is not PCLinuxOS Standards stable.
My PCLinuxOS, LXDE version is installed in the computer I use everyday (8:00 to 18:00) at work, and that's because I know it simply works, I don't have time to fight with the OS or the programs to get things done or pull my hair because a glitch (or God forbid, a virus) avoids the use of a program or bans the access to a file.
So, you're right, testers are very valuable in this process, wish you the best luck in that adventure.
