Same here. I've been in the chip design industry since 1997. Everything was Sun and I was right out of college and convinced my manager to let me use a Linux/x86 machine and I used the savings to buy a large 21" monitor that would run at 2048x1536 resolution and use it as an X terminal to the Suns. Everyone else loved it and did the same.
Around 2000 we started getting some EDA software released on Linux. I remember getting some Linux kernel patches and recompiling the kernel to change the user / kernel split from 2GB / 2GB to 3.5GB user / 0.5GB kernel. But we still needed the 64-bit Suns for some jobs that needed over 4GB RAM. Itanium was really expensive and slow and then AMD released the 64-bit Opteron in 2003. We bought them immediately and never bought another Sun.
My high school in 1992 got a bunch of old Sun3 and first gen Sun4 systems. I absolutely loved them. My dream then was to have my own Sun workstation but they were way too expensive. My other dream was to go to college and then get a job at Sun. I heard about Linux in 1993 and got my Unix system at home. I did work on some Sun UltraSPARC III companion chipsets but Sun couldn't compete on the price to performance ratio with Linux/x86
We had the Sun workstations in college (some with that crazy laser mouse) and I think towards the end of my tenure, most of the labs were switching to linux boxes, but at that same time Solaris x86 actually came out - so on commodity hardware you could run Solaris which was kinda fun.
I did this a little, but the things you could do with actual Linux started to get interesting for me at that time - building routers for our shared home network, hosting Quake servers, doing actual programming with gcc etc and the hardware support was a bit better as I recall.
I also interviewed at Sun in Boston - I think the small group servers group or something - I really liked the engineers I met there and I did consider working there for a minute, but ended up in Silicon Valley which I think was better fit for me.
