Windows-On-Linux Emulator Shootout
securitas writes: "ZDNet has posted a comparative review of 5 Windows-on-Linux emulators from VMware (2), NeTraverse, WinToNet and Wine." The results encountered varied quite a bit -- none of the products are perfect, but it looks like they hit a particularly disappointing time with Wine.
If you have the funds, buy two computers and a switchbox. If you don't have the funds, configure your machine to dual boot.
Really, what's the point of running the emulation if you lose speed and capabilities?
