Most people’s needs are satisfied with just a home computer and Internet. A wireless network will typically suffice. I have a lab as well as a home network. I like to keep my skills current and run a lot of “what if?” scenarios through various tests. I used to build up this environment over the years and keep things current. The lab consisted of nine PC servers, two laptops, PC workstations, Mac Mini, iPad, etc. This is my playground and technological paradise.
Today, I have one or two high-end PCs and do almost everything through virtualization. There’s so much processing power on a single PC these days that one doesn’t need many computers. The electrical bill is much lower as well. Platforms like VMware and Citrix XenServer are essentially free, it only makes sense to virtualize.
