How memory-intensive is VMWare workstation? I have a P4 3.0GHz with 1/2Gb of memory at home - is VMWare going to be a total drag on the system or is it lightweight enough that I can still run (as opposed to walk or crawl)? I run VMWW at work, but that's a Pentium-D with 2Gb of RAM, and top shows vmware using 199m virt, 1.1g res and 1.1g shr - not sure what that means (but it looks like bad news for the home situation...). Thanks.
