I was one of those people that had every possible peripheral that I would ever need hooked up to my Mac and ready at all times (printer, media card reader, external HDD, iPhone / iPod dock, wired ethernet, external monitor, keyboard, mouse). I even had this setup for my PowerBook G4 when it was at my desk. I never ever used a trackpad -- I always hated them and used a mouse for my notebook computers. But since getting my MacBook Air and an AEBS, I have completely changed that setup. I have the external HDD and printer attached to the AEBS. With 802.11n, I find the wireless network to be quite fast. I have come to love the MBA's trackpad and never use a mouse anymore. I hardly ever use my external monitor now. I don't even miss the optical drive either. The only time I've needed one is when I installed iWork 08. I now take the MBA everywhere -- in fact I do more work away from my desk now probably due to the sheer size/weight of the MBA. I'm just curious, has anyone else had this kind of change in their setup/behavior since getting a MBA?
