I am a lifelong Windows user who has "had it up to here" with Microsoft. I have a considerable investment in hardware, obviously, so I am considering going over to Linux. Someone told me that I should consider Leopard. That because Macs now use Intel processors, I could install Leopard on all my current Windows PCs. Is this true? If so, how difficult would it be to set it up as a dual boot system so I can slowly wean myself off of Windows? Thank you.
