I'm still on Tiger (10.4.11). That's because I'm on PPC macs only (iBook and mini), and Leopard was the first OS release that was actually slower than the old OS it replaced (unlike f.ex. Panther was faster than Jaguar, and Tiger was faster than Panther on older hardware etc.). Leopard is bloated compared to Tiger, and far more buggy upon release (and delayed, because even Apple themselves admitted they pulled the engineers off Leopard development, to throw them at the iPhone). In fact, compared to my 2 friends on Leopard, my 10.4.11 is still far more stable (they have endless problems, especially with wireless and internet connections, and so on). In fact, one can see Snow Leopard as the OS that Leopard should have been, had it not been done half-a$$ed and hurried sloppily. So they are going to release SL with "no new features" - just Leopard as it should have been in the first place. Tiger has been rock solid for me. The problem is that my hardware is getting old (3-4 years), and I need new hardware. I consciously boycotted Leopard - I simply decided to skip the 10.5.x releases. Now is the time to get new hardware, and with it, Snow Leopard. I hope it will have proven worth the wait. Here's what I'm hoping for: 1)Stability - yes, I know any .0 release will have some initial bugs, but I'm hoping it won't the be the horror 10.5.1-2-3 was. 2)Speed increases. I'm hoping it is significantly faster and not as bloated. 3)That they fixed a number of issues with internet connections being dropped, with Time Machine being wonky, with Spotlight still useless after all these years, with Finder finally being more than a toy and a few more annoyances. So, who else here is on Tiger with no real experience of Leopard? And do you plan on getting SL? I'm thinking of getting some hardware late October or early November, maybe by then we'll have 10.6.1 out to fix some initial bugs.
