Ok, so I guess approximately 99.9% of you stopped reading after the title. "Solaris? What is that, the sun?" Well, actually, it's a Linux distribution (distro) put out by, guess who, Sun Microsystems (would never have guessed =]).
Anyhow, if you're the kind of person who flinches at knocking a ~5gb chunk out of your hard disk to store a Solaris Express Developer Edition (sxde) image, fear no more. For a limited time, you can get a free sxde DVD mailed to you (although it takes about a week and a half).
I've got a copy or two in the mail, so I'll see how I like it.
By the way, for those of you wondering why this is so great, the only other Linux distro that gives you free CD's at this time is Ubuntu. I also have a few of their discs =]
