I'm kinda sick of rebooting, since I usually put my computer to sleep when I'm not using it. Boot Camp is great software, but I really want either Parallels or Fusion. Which one has a better interface, support, cpu usage, etc. Please convince me using facts and not just opinions, although they are welcome. Which one works better? Also, I have a bootcamp partition, I've heard ppl say that one virtualization program or maybe both will accept that drive. that saves me alot of backup work and time. Which one will use an existing bootcamp partition? or both? thanks so much!
