I remember buying my first Sun workstation, an Ultra 10 with a 440MHz UltraSparc CPU with 512MB of RAM with a Creator 3D graphics card. I ran Solaris on it for a while, then put Red Hat Linux 6.2 on it. It was my main workstation at the turn of the century.
I also had my share of Sun migrations -- away from Sun. Back in the dark days of the early 2000s, more than a few companies were looking at the cost of their Sun contracts, and this up-and-coming Linux operating system, and exploring alternatives. I can recall replacing SunFire V440s and 280Rs with Dell and HP servers running Linux (unsupported at the time) and showing performance increases in the triple digits. I clearly remember walking into a datacenter that I had just finished moving to Linux and taking a long look at all the Ultra 60s, V440s, and 280Rs lining bakers racks near the door -- powered off, cold, and silent. A dozen feet away, half a rack of first-generation DL360s were humming along, running Red Hat Enterprise Linux 2.1.
I remember unboxing several Sun Netra X1s and wondering what happened to make Sun produce such a terrible server. I also remember talking with Bruce Perens about Sun and Jonathan Schwartz at LinuxWorld several years ago. We decided that the pony tail is usually found at the back of the horse, not the front.
I remember buying six Sun GDM-5410 21-inch CRT monitors at an auction for $100 each. I still think they were the best CRT monitors ever produced. I still have them. All but one still work flawlessly.
I remember my surprise at Sun's announcement of the first multicore Sparc chips and the introduction of the Sparc T1. I was also surprised at the announcement of OpenSolaris, and /usr/sfw, which contained a whole pile of open source tools, services, and applications that suddenly came with Solaris and didn't require half a day spent pulling packages from sunfreeware.com and blastwave.org.
I remember Sun buying MySQL and thinking, "Well, I hope they don't mess it up." They didn't -- so far. Apparently they were waiting for Oracle to give it a shot.
