Microsoft Tech Note What a laugh and a half... so many places/people have tried to pretend like the upcoming Athlon64 is a good option for desktop machines but when you look at the facts, you would need to dual boot 32 and 64-bit XP... WHAT A JOKE. I hope Apple pushes the G5 like they have never pushed a machine before because there is SUCH a brilliant opportunity here to capture a great deal of the market. Maybe Panther is not a "true" 64-bit OS but it allows people to actually use their 64/32 machine in an effective manor while utilising the features of a 64-bit system that desktop users would actually be implementing from day to day. To finish up, here is a note from Microsoft that you will NOT see associated with the MacOS: Using an emulation layer, you can run 32-bit applications on Windows_XP 64-Bit Edition. However, such applications run significantly slower on the 64-bit system than on the 32-bit system, because emulation requires additional resources.
