You don't bother with things that can easily be replaced by an alternative. It gets too competitive. Good luck with the soundbar, it doesn't matter the quality...the fact is that it can easily fill that other person's needs. Same goes for television...that's a waste of time IMO. People generally don't care about contrast ratio or any of that other nerd shyt as long as it meets very loose requirements for them. HDMI Ports, 1080P, etc etc.
You are mentioning things that can be satisfied with cheaper alternatives...so I can tell you have tried. It has to be in high demand and a product that nobody else can make. I will never touch android phones outside of Samsung phones because people love those things...it is THE android phone to sell quickly. I can tell people that I think the HTC One line is better than the Samsung Galaxy line until I pass out, but it won't mean anything. One they are both android phones, two? Samsung is more popular. Waste of time.
