I have a SunBlade 100 at work (Solaris) and a 1.4 Ghz Athlon (Linux) at home. Both have .5 GB or RAM or better. The SunBlade is nice, rock-solid hardware, but I would not trade the speed of my Athlon for anything. In fact I spend about half my development time at work SSH'ed into my home box because it runs so much faster. I copy the code over, develop at home and copy it back. Plus that way I can links into PM.org whilst I work. ;)
