well thats your opinion and i merely gave mine. frankly for a
primary computer, i hate using a track pad
see the 2 usb on the mb gives me one for my kb and mouse and the other open to a usb hub
i also dont have to tie one up for an optical drive if i want to watch a dvd or if i need to use ethernet.
many including myself use external hard drives and that requires usb or firewire
so yes, one usb port that must be used for an optical drive, ethernet, ipod, hard drive, keyboard and mouse, would drive me insane
another thing, dont post a question on whether or not a mba can be used as a PRIMARY computer and expect to have all the replies echo your needs. i stated my opinion on what i want in a primary computer as this thread was asking about using a mba as a primary
if you dont like dissenting opinions from your own, then dont post the question.
your reasons to me justify it as a great secondary computer. i merely dont see the logic in it being a primary ok. but hey whatever floats your boat
for the record, even my mb is not my primary machine as i use a desktop
