Very sweet, but I don’t have a need for one.
But here shows why Apple always has the best designs. Every other manufacturer tries to shoehorn existing chips into their notebooks, while Apple actually got Intel to design a smaller one.
No optical drive doesn’t bother me given the market for these. Use a USB key if you need detachable storage, they hold more than a dual-layer DVD anyway. And a Mac can boot from them.
One USB port is not great, but I don’t see much other option given that a USB port is pretty big. The only other answer would be to sacrifice a lot of compatibility by using a smaller port and requiring an adapter. I can see that for the video, but not for the ubiquitous USB.
No Firewire isn’t great, but then this isn’t a machine to be doing your high-speed video editing on anyway.
No Ethernet, again port size problems. It has N, so network transfers won’t be too bad. But again we come to the market for this, probably not people who will be shipping tens of gigabytes around all the time anyway.
In the end, Apple packed more power and usability in such a small space than anyone else has ever managed. It’s not missing too much compared to machines that are two to three times its volume.
Apple is selling a USB-to-Ethernet adapter for 10/100BASE-T for $29.
