I have an 11 inch MacBook Air (2010 model). I'm tempted by the new Magic Trackpad but I wonder if if will just end up being redundant with the built-in trackpad? Is there a big advantage to the Magic vs the MBA's trackpad?
Well I have a 13 inch MBP that I connect to a external monitor in clamshell mode. I really do like the magic track pad because I can use all the gestures that I normally use on the MBP trackpad. I think its work it if you connect to a external monitor and run your MBA in clamshell mode.
