Pros 1. Unit allows you to use your iMac as a display for HDMI outputted devices. Works great...when it works! 2. No lag when using the device with a game console.
Cons 1. Unit failed after 2 days. 2. The process to connect your HDMI device with your iMac is annoying. 3. No phone number to directly reach Kanex tech support. 4. Some images/text aren't as clear - displays more pixels compared with stand alone TV.
Summary When you follow the directions on how to connect your devices, it works very well. But based on my usage, failure after the 2nd day may point to a design issue. The issue with some images and text displaying more pixels than a standard TV/monitor may not be acceptable to some users.
Pros Allows iMac 27" to show virtually any Blu-Ray source
Cons Price / Connection routine - HDMI (from Blu-Ray source) > Kanex XD / Power > Kanex XD / Mini Display (from iMac) > Kanex XD / Connection process must be followed each time after a power down
Summary Can't add much more than what's already been said by CNET. IMO 720p Blu Ray looks good on iMac 27" screen so I wouldn't call it "crummy". I like toys so $150 wasn't a deal breaker (the HDMI and Mini Display Cable are probably worth about $30). I found that performing an upgrade on my PS3 necessitates a manual reset to 720p resolution - so be forewarned. Have played several Blu-Ray movies on my iMac with no problems or lag. Using a good 2.0 or 2.1 speaker setup will offer excellent sound reproduction - I use a Creative Gigaworks T20 Series II 2.0 setup (contemplating upgrading to 2.1). I recommend the Kanex XD if only to add a little more WOW factor to an already superb display.
