My complaints:-- The keyboard backlight goes out after 30 seconds.  This cannot be disabled, even in the BIOS settings.  The single most annoying thing I've ever experienced with a notebook.-- It's just unbelievable that Acer didn't add a notch, finger groove, etc. to the clamshell to help you get the darn thing open!-- The touchpad takes a little getting used to.  I also have a MacBook Pro, which has what is probably the best-regarded touchpad in the business.  The Acer pad frustrates me sometimes, but isn't too bad.  As I'm resting my fingers on it while scrolling around a page it often thinks I'm right-clicking.  I reduced the sensitivity but it still happens.  I'll try reducing it some more.
