I'm not upgrading to Snow Leopard until at least September 2010, i.e. one year later after launch. As you can see, it took at least till 10.5.6 for Leopard to get fairly stable. I was one of those suckers who upgraded to Leopard on its launch day (I have the T-Shirt to prove it), and spent the next week in sheer terror trying to resurrent my dead Mac with a decade's worth of photos in limbo. Then the next 9 months waiting for each fix that eventually got Leopard stable. So, thanks, but no thanks. I can resist the TEMPTATION to pay $29 to volunteer to be an Apple beta tester. Seriously, here, for SL, it is a case of you guys simply cannot control yourself. Most of the SL features are just cosmetic. You won't see the under-the-hood improvements. Sure, SL will be much faster, but is that going to change your life dramatically, such that you can risk the bugs. I use my computer for work and business-critical work. I guess you early-SL-adopters don't use your computers for anything that's not life-changingly-critical. Of course, you all will respond by saying that I should make backups, but what if SL's bugs extend to Time Machine's backup software, as it did in 10.5.6 -- for which I had to wait till 10.5.7 for it to be fixed. No, I'm camping at relatively stable (hopefully) 10.5.8 while you guys proceed with "long periods of boredom punctuated by moments of sheer terror".
