Is there really a huge difference between the 2? I've heard that firewire is the way to go, but my PC doesnt have firewire. My friends with Macs keep telling me that recording with PC's isn't as good as with Macs...how much truth is there to this statement. My comp. has 1.6 Ghz intel, and 512 MB ram....I'm looking to buy the Digidesign M-Box or somehting similar...does anyone have any experience with the Mbox? what are ur thoughts?
