I have heard that the UI lacks flair. The thing that the Roku will not do is extend my mac mini desktop. I download F1 torrents and would love to not have to unplug the mini and hook it up to the TV to watch them. :) Chalk it up to pure laziness on my part. Other than that 1 feature, I would go get a Roku 3 tonight. I will wait to see what Apple TV 3s or New Apple TV or whatever name they will come up with for it has to offer.
