The bigger issue is Samsung's own lineup of smartphones. The Galaxy S2 and S3 smartphones with the HDMI adapter plugged into a large screen is like having a pseudo computer as well. I have the Galaxy S2 and I surf, watch videos, email, text, play 3D games, etc through my 50" 1080p display. To boot... it fits in my pocket, lasts 12-14 hrs a day, take 8 megapixel pictures, record 1080p videos, and wow I can make a phone call with it.
In the next 18-24 months netbooks, nettops, even laptops and tablets will be "novel" devices... smartphones with cradle/docks to work like computers will be the norm. Suddenly the Samsung Chromebox seems silly and expensive.
