what a fantastic machine the mac pro is. I've been a PC user for twenty years and have built several high end machines but this piece of art takes the prize. I've never seen a more well built machine. The outside looks gorgeous - the build quality would put Lexus to shame with what looks like aircraft quality aluminum. But the inside takes the cake. It's so well designed - adding hard drives is a breeze. A lot of thought went into this - kudos to Apple designers. Oh - and the operating system is great too. I dual boot to Windows XP (for business apps) and the difference is striking. Ah well enough ravings. Alan PS I could say the same about my MBA too - I've gone whole hog on Apple this last two weeks MBP, MBA, ATV.
