A lot of the newer Blue-ray and smart TV's have Wi-fi capability built right in, which enable users to stream Youtube, Amazon Instant video, Netflix and the like easily.
I went to Best Buy recently with the intent to buy a Roku. While there I noticed a Blu-Ray with streaming capability and it was much cheaper than the Roku 3. When I asked the clerk if the streaming on the Blu-Ray was somehow inferior to the Roku he looked at me like I was crazy. He couldn’t explain anything. I left without buying anything and I still haven’t.
I am sure there are Best Buy clerks who know their products, just like there are a handful of Lowes employees who actually know hardware, but most at both places are worthless.
