I upgraded, found some glitches, incompatibilities and annoyances, and almost immediately went back to Tiger. Then some fixes and tweaks came out and I gave Leo the benefit of the doubt and reinstalled. Then I found even more glitches, incompatibilities and annoyances, and went back to Tiger again today. I'll be waiting until Photoshop, Lightroom, iSnip, Max, SuperDuper, Candybar, SafariBlock, Spotlight/Finder searches and the DMG unmounting bug get fixed or become compatible. Also waiting until TimeMachine sounds more stable and Stacks get some more powerful options. I wanna like the Leo. For now I can't. *Crap. This was supposed to be a poll but the server hiccupped.* Have you Leopardized? 1. I'm still waiting. 2. Yes, I upgraded and I'm lovin' Leo. 3. I upgraded then downgraded. 4. I upgraded, then downgraded, then upgraded, then downgraded. My S.O. is so sick of seeing me at the computer he/she wants to pour syrup on the motherboard.
