The Solaris binary downloads do not include the "Companion" CD with Samba, etc. on it, or the Star Office and Oracle CDs that come with the media kit. For my money, buying the media kit is the much better way to go. But if you're in school, money is tight, or maybe you just want to play around with Solaris a little without investing a chunk of cash, at least downloading the two "Software" CDs will get you up and running. So if you've got the bandwidth and you want to take the download route go to following page. Only download the "Software 1" and "Software 2" CD image files. As you will see below, you don't need the "Installation" CD. If you're going for an English install you also don't need the "Languages" CD.
