This really reminds me of the original iMac. When it came out, USB devices were pretty rare, but this got better pretty quickly, especially regarding printers. Firewire wasn't as successful. Although, if I understand correctly, you can just hook up an external PCI-express bay via thunderbolt, so you don't really need special hardware (like e.g. USB audio devices). So apart from the usual series of external hard drives, you'll probably find a few expansion bays docket to your central ash tray. But given the additional power bricks, wires and boxes you need for this, it seems they're optimizing for the non-extended situation and/or want to give their other computers equal footing.
