I just formatted my drive and installed Snow Leopard. Having always been a person who has to have the latest gadget/computer/software, I purchased OS X Lion the day it came out. What a mistake. A few of my least favorite features. Though I googled several different articles about disabling the opening of documents and apps during a reboot, I never could get it to completely stop opening them. It would still have the check box that I would inevitably forget to check upon rebooting that would then cause a 10-minute delay (not really but it seemed like it) when booting up while acrobat/photoshop/indesign/word/excel/outlook started. I don't get this feature. If I want a program to start, I can pretty easily click it on the dock and start it. The one I really enjoyed was the software update a few weeks ago that disabled my HP Color Laser printer, and made it impossible to print to it even with the generic PCL 5 driver. It simply stopped working. This wasn't on the lion install, it worked for 3 months after installing lion, it just stopped one day after an update. No mind you this printer was just released in May 2010. My Canon printer also doesn't work any longer. This was released 3 years ago, so it is not that new, however the canon download from apple states that it will work. When installing the printer though, I point to the newest downloaded driver, both from canon and the apple web site, and get an error when the OS attempts to download its own driver. I feel better now as I write this from my fresh Snow Leopard install.
