I think you will see it grow, even if slowly at first consumers will eventually evolve (as a matter of fact one of my business models is counting on that) Like buying shoes, it took people a some time to get used to buying something without seeing, touching and trying on, then Zappos came along and eliminated hesitation with exceptional customer service and no obligation cost free returns. Eventually consumers will overcome their doubts and then like with so many other technology driven conveniences, become addicted. - Chef Mickey
