The new MacBook looks pretty dang sexy all small like that but it’s only got one port. I know on my 13″ Air I went with a dock from Startech so I could only plug in a single Thunderbolt connector and power and the 13″ has 2 USB ports.
If you’re looking at the new MacBook then check out the Hub+. It’s going to allow you to have a number of things plugged in to your MacBook…and charge it at the same time.
It’s even a batter for your mobile devices so you can charge them without even needing to plug them in to your MacBook.
