Not sure what you bought in the end, but I am a Macbook Air user and am very happy with the unit. I dropped it once, and it caused the internal fan to ocassionally stop spinning - Apple fixed it in 24 hours for me after dropping it off at one of their stores. Apart from that - no issues.
I don't use much in the way of external devices, just the odd external drive, usb memory key or 3g adapater., so tha lack of ports doesn't concern me at all. USB hubs are cheap for home use, and a small travel hub can be good to leave in the bag.
