I really think it's mostly because Linux still requires a high degree of techyness, and the product and hardware support isn't great unless you really know what your doing. It's still a pain to get flash or java on ubuntu, openoffice won't deal with docx formats, powerpoint isn't available, printers are a pain to set up, even modem support is complicated and bad out of the box -- I had to setup a virtualization layer just to get my wireless working. It really shouldn't be any wonder it's not getting widespread adoption; there are confounding factors, but I don't think we need to posit price signaling to make sense of this.
