"It's been said many times here but I'll say it again, if you cannot tune a guitar properly yourself don't even bother having one, tuning was one of the first things I ever learned by myself.
We will end up with them as standard on everything one day though, but for now, we need to make such horrible devices obsolete!"

The reality of these things is you can still tune it yourself. that's why it still has tuner knobs..
I used to tune by ear and touch(yes I could feel the harmonic) now-a-days I have a couple of little electronic meters that tell me when it's spot on, and I am sure most others do too.
