OK, look, I'm going to try and reply to this in the politest possible way, but sometimes I find that difficult when faced with statements like this.
I really don't understand where people get off preaching about other people's business decisions. In what way is Dell installing whatever software they like, on a computer they build and sell, "wrong"?
What law of nature states that computers shouldn't have logos on them? The non-t-shirt-turing-machine-no-logo law? I haven't heard of that one.
OK, I'm done now. I'm perfectly happy that you make aesthetic and technical decisions about software and hardware, but don't go calling people who engage in voluntary trade "wrong", or telling them what they should or shouldn't do.
Just Don't Buy It.
