There are enough port bits for some thousands, I'd suppose, but does that work in practice?

So there will probably be a limited selection and they will probably be rushed out. So it would be easy to imagine a big deployment of hardware with likely buggy firmware. It will be just like the good old days! (Has anyone else been following http://www.wiredreread.com/ ?
