Where do I begin? After looking at the blank page for a while I think I'll go in chronological order.
Born in 1974 I had the chance to grow up in the era of home computers and early personal computers (in the IBM sense). I was a nerd back then and so I read all the more advanced computer magazines I could acquire in my little hometown. I have very fond memories of "mc" which sometimes included market overviews of highend PC workstations and "real" workstations. I think that is where I have become aware of companies like Sun and Silicon Graphics.
Fast forward to 1994: After school I joined our army for compulsory service. It was not my choice but I do not regret the time spent. I made a lot of friends during the months and a couple of them I still see on a regular basis. Technology wise I got the chance to get into something like an IT department. On my first day I was stunned to see a real life Sun workstation in our office that some company "forgot" after doing a presentation. That's when I learned that a Sun IPX already felt slow in 1994.
Another fast forward to ~1999/2000: When I was a student I started to fiddle around with Linux. That's when I figured an old real workstation with a real UNIX could be an interesting option. After a couple hours/days on ebay a full SGI Indigo set with CRT and install media caught my attention. I bought it in 2000 and that's when the whole retro/workstation computing madness started for me. The ride lasted for more than 10 years and it was great fun. My "active times" as an SGI hobbyist ended a while after the real SGI finally died when it was acquired by Rackable.
This is the first Indigo btw:

Currently I am working in consulting (tax/law) and I have no connection to the IT business other than a couple of clients that do IT consulting. I still have my workstation collection, most of it is in storage though.
