I'm a recent Mac-convert, and as much as I love my iMac, I've never experienced these problems with a Windows PC before. Waking up from sleep, there are random connection issues with the internet (it is not my router; I've checked), and more commonly, problems with my mouse settings being properly activated. What I mean is, when waking from sleep, sometimes my mouse speed is entirely different, my hot keys aren't in place, and the scrolling speed is different; meaning not the settings I picked. It requires a reboot for the mouse to be working "properly" again. It's a logitech mouse. The weird thing is, when I go to configure it in my settings, all the settings I picked are in place. It's as if the mouse just isn't registering the configuration until a reboot. I've never had these problems before with my PC. It's frustrating to experience such simple problems with my Mac, especially from a company that sells "premium" products which are supposed to "just work." I am on Lion, so perhaps it's a Lion issue, but regardless, it's displeasing.
