Guess what I saw in my local Comp USA, which had been noticably absent for I think almost a year?
Yup, they started selling shrink wrapped, boxed, Linux distros again, and more than one. They had SUSE 10.0, three different versions of Xandros (you know, basic, advanced, and more expensive professionial with StarOffice and other stuff in it), and two versions of Linspire.
No FreeBSD though.
This, overall, I think is good. There's a lot of advantages to buying a distro over downloading one. You get Multiple versions (x86 and X86-64), multiple media (CDROM and DVD-ROM), and support, a printed manual (a real book), support from the company, and you usually get a bunch more software on media than you would by downloading...
For example, when I downloaded FC5, a great deal of the software that I wanted wasn't included in the download. I learned later that I could get it through YUM, but that took time. When I had bought RH9, most of the software was on RPMS on an extra CD, saving download time.
