I think this is only a problem if you're targeting niches because as I see it, if you can't use your own product while pretending to be your non-technical mother, then you shouldn't be in business unless you're selling for a premium. Unfortunately, technical geeks won't pay a premium and they themselves can often build something relatively useful with, in this case, even a simple google search:

I actually went through this exercise before and found it to be annoying, but how often do you search for and buy books? It's not everyday you do.
Don't get me wrong, I've bookmarked your site and find it useful, but I probably won't go back to it in a while.
