How many companies sell suits vs how many companies sell barefoot running shoes? I mean, if you had to write an article on this subject, who else would you mention? I guess you could say "Nike, Adidas, ASICS, and Reebok don't offer any serious products for this market yet" but that's a bit like mentioning that Microsoft, Palm, and RIM didn't offer a serious competitor in the market of touchscreen smartphones right after the iPhone came out.
