but my question is, why isn't it popular then?
I think that it's not popular, is that if ever computer had one of these, then there would be no need for Tech Support related jobs, no more having to take your computer into the store and pay top dollar to get it fixed, so i doubt that repair type stores are going to advertise it to ther customers, as they will loose when customers stop coming in, cause they were able to fix there own computer..
