Hmmmm. Not sure I'd call it a hand tool, but I'm using an AMD 2.1 Ghz for the CNC in the garage. Also in the garage is a PII 450... Yuk, but it lets me tinker with stuff while the CNC ties up the other machine. For CAD, toolpathing and other more general stuff, I have two machines indoors. A 64 bit AMD 3400, and a 64 bit AMD 2800. Besides that, there is my server (AMD XP3000+). Oh and a laptop incase I need to use a PC while I'm on the toilet.
I hope you like your new Dell laptop. Too pricey for me. Does look the biz though.
