As somebody who's company has just sunk some serious change into PowerPC-based Mac hardware (namely a bunch of XServes) and someone who's not watched any of videos about Leopard. I'll be very interested to see how long until Apple's entire range is Intel based. Especially when our playout and production won't run on Intel machines currently!

BTW, Time Machine looks really cool. I assume that means that you never really delete anything. What if you want to clear space on your machine?

EDIT: Wow, just configured my 'dream' machine, I say configured. I just clicked the most expensive option for each thing. A mere snip at just over £11.5K
