a box seems a wiser idea than a tv. this way, you can move it around. Plus, if TV dies, you still have the box or vice versa. I think better to keep them separate as much as I like the Sony tv's. Plus, the Sony TV specs lack faster 120hrz refresh rate and use lower 60hrz and that is a deal killer for me as I need faster 120hrx to reduce the motion blur from action movies. As well, the Sony tv's use Edge Lit LED versus array LED. so, I think the box will be the better way.
and yeah, I likely will buy one. I LOVE the idea of surfing the web from the couch and being able to have a PIP with tv running and the web. Often, we will watch TV and want to find out about something and have to pull out the phone. being able to do it on the TV is just a nice convenience, but I will wait until I can get for less than $300.
