I've started to get myself familiar with MIPS in preparation for a spring course. So far, I love the control you have. I've never had to think about some of these things and you get an entirely new perspective of programming by doing just a basic amount of assembly. I can't say I could use it in my everyday work environment but for a hobby, I could certainly enjoy it. I went out and found the AMD Athlon XP processor specs, so I hope to get into that shortly. Hopefully they aren't that much different.
