How are you to be sure what above-average salary is? You may think you are asking for above-average but instead just asking for average. Your better selling your self as above-average and use that to bump up the salary after their initial offer
That's where I'd put my money, too. Several weeks ago I was sitting at my laptop and I wanted to scroll down on a web page I was reading. I instinctively wrapped my hand around the bottom-right corner of my monitor and brushed the screen with my thumb.
A week later I was in an Apple store and a young kid walked up to an iMac and said "ooh, I bet this is a touch screen". It wasn't, of course, but it made me wonder if Apple hasn't been quietly training a generation of people to expect to be able to touch the screen. Maybe that's what the much-maligned glass displays has been about: user preparation for the inevitable day.
