I personally don't care for the MBA... especially the multi-touch. It's great on the ipod touch/iphone but on a laptop I hate it.
They swipe and pinch stuff on a laptop are silly gimmicks that would take time to get used to. Especially if you have other laptops...
I really do believe that they are just those types of features you show to your friends so they can be jealous
They only feature I really like is two finger scoll, but I already have it.
I'm pretty sure this is an app that adds gestures to a regular macbook touch pad, but I can't remember the name of it for the life of me. Could someone please post the name?
