The previous comments mentioned poor contrast and small text for visually impaired. I have great eyesight and I had a hard time reading your site. I had to literally select text in some areas to even be able to read it at all, combined with zooming in. (I have a 27" monitor!)

That being said, I really hope you succeed, I really want a repairable long term phone in the future. Not sure about what B&W adds to this, but it you offer a chopped down cheaper version (along side your flagship phone), it's far less of a risk to give it a try.
