With your point on vista I just couldn't disagree more. Vista uptake has been slow as admitted by microsoft. It's complex HDCP built into the OS actually slows it down, in contrast to Leopard which speeds up the interface in hardware as old the G4. 10.4 is very stable, and though Leopard lacks that for the moment, Vista which has been coded mostly from the ground up will continue to produce problems, whilst Leopard's strong base of tried and tested coding will ensure cool runnings once the kinks have been ironed out. Time machine is exceptionally usefull to anyone whose livelihood depends upon their data. Many security firms have claimed Vista is LESS secure than XP. Oh sure some companies will make the switch because their IT departments will want to look proactive, but consumers are moving away from the wintel platform as microsoft have failed to deliver much except a graphical improvement. In fact as GNU-Linux gains popularity and products such as 'Ardour' (open source DAW software) will probably take over from Logic, PTLE, Cubase et all. It may sound impossible but open source software develops much faster than the proprietary because development because good code can be reapplied, and redeveloped at a rate that 'greenfield' software cannot. I'm not advocating you move right away and ditch you're most loved plug-ins but it's a ridiculous position to slate leopard as simply a feature based improvement when it provides full 64-bit compatibility (which is important if you're using more than 4 gigs of ram), resolution independence and other 'under-the-hood' changes that lay the foundation for important development on the platform.
