Firstly, there is a real market need. Every device on the market has it's trade-offs. The HTC One has the nicest feel in the hand and a stunning screen, but the camera and polish of the Android skin leave something to be desired. The iPhone and the Lumia have stunning cameras but each have their own tradeoffs. The Galaxy S4 has a nice camera, but a horrible plasticy feel in your hand. And virtually all phones sold today demand a case.
If you want the best phone on the market, not only will you need to compromise, but you will be just one of millions of other people sporting the exact same handset. The non-conformists, Apple and Samsung, have gone mainstream. And there is no better time than today than to start a hardware startup.
This limited run, premium handset would be sold at a serious premium - think double the cost on a carrier contract of $200-300 higher than the standard off-contract pricing. It would have the best specs on the market, stock Android, differentiated design and a stunning build quality. Not only would it look great, but it would be solid enough not to need a case. If Blackberry could figure out how to make a phone that didn't need a case in 2006, I think we can work in out in 2013.
Our innovative mobile world has gone mainstream. Someone, somewhere is going to think different. The market demands it.
