OK then maybe that's not a computer for you and your kind of work. I think it's personal. As a nomadic front-end developer, I'm really happy with it. I would be equally or more happy with one port more, no doubt, but it doesn't feel like a problem to me.

Until they switch to single-port across all their devices this is a non-issue. You still have other options in the MacBook Air and MacBook Pro lines.

I write apps for iPhone. I have a dongle that gives me power, connects to my iPhone, and connects to an extra monitor.

I'd rather carry around a dongle that weighs less than an ounce than add 2 lbs of weight to my laptop to accomadate more ports

Does it really add 2 lbs of weight to add some USB ports?

No. The MacBook Air isn't even 1 pound heavier.
