Most of those are redundant now that we have USB 3. The network port would be useful, but I guess most people just suffer with wireless now. It really sucks that they don't include a headphone jack, though. As much as Apple tries to be a company for 'creatives,' this move is baffling. The only way to get audio out is over shitty bluetooth. That means it's always compressed and distorted, and therefore completely useless for professional work. Oh, but there's lossless Bluetooth now? Sure, it exists, but you can't actually use it if you have WIFI or any other Bluetooth accessories.
