One of our gifts this Christmas was the new Mac OS X leopard family pack. We are all enjoying the new features which this new kitty brings to our computers. I especially enjoy 'stacks' - a cool way to keep your desktop clean, yet files and recent downloads a click away. Another feature that I have already used a lot is the new interface between mail and iCal/Address Book. Calvin likes the 'cover flow' feature. We will be discovering new features as time goes on. Mac users, if you haven't upgraded yet, do it. PC users, just hope that someday Microsoft will steal some of these features in a future OS.
