You tried it and said it hadn't broken anything ;-)
I went the early adopter route after all because after sitting on Tiger so far past its usefulness and watching other software upgrades thumb their noses at me in a steady parade, I decided to roll the dice and make the move now.

Plus for years, my two Macs were out of sync. The MBP that I just replaced was light years ahead of my Quicksilver G4, and then when I replaced the G4 with then Mini last December, it was extreme leapfrog. So now, I have two Macs that are at total parity. Balance is a good thang... grin
