Doing a proper HW project from scratch is really risky. To keep up in long run is even more so. Just look a Pebble who even though delivering multiple products simply burned through all investor money and went down.

Despite the clever marketing of some "groundbreaking" features the first iPhone was not a big commercial succes. Just the followup generations with lower price and app store had a breakthrough.

You need a lot of upfront investment and can be never sure if it will be worh it. For that reason I really honor anyone who tries to produce some quality HW. Especially in some niche market lke HWKBD phones. :-)

So keep up Chenliangchen!
