This was my first CES, but I think that's quite evident. While I found many small, and awesome accessory makers in the iLounge Pavilion, there's TONS of stuff scattered about the show floor. Actually, I found most of the CES "techzones" poorly labeled. HigherEdTech barely existed, and while PMA did contain photo stuff it was so far from the actual camera makers (Canon, Nikon, Polaroid, Pentax, Sony, Panny). The same applied to the MommyTech and Fitness and such.
Tough, I can't really fault the CEA for poor organization...the show is just too huge.
Anyway, there is always going to be lots of neat stuff for Mac users, that aren't even marketed as Mac accessories. Cameras, Printers, and TVs, and even processors as all relevant to Mac users.
On the side note of TVs...has anyone tried plugging in an AppleTV to a 4K TV or monitor? I'd suspect the result is simply upscaled 1080p, but I'd be curious to know if anyone had problems or if there was quality improvement or not.
