Updated to 10.7.1 last night. Unfortunately the mouse pointer acceleration issues aren’t resolved, but network connectivity seems to be way smoother (over the past week I’ve occasionally had to reboot the machine to get the network to work).
However I’m now completely “sold” on the new scrolling (reversed like the iPhone/iPad). :P. That and the new Mail.app are nice. Really looking forward to 10.7.2 or what ever the version is that will resolve the erratic mouse pointer acceleration.
