While I appreciate the thoughtful analysis, I have been an Apple fan for thirty years, and I won’t switch to Microsoft even if Apple has a bad round. Why? Because the aesthetics are a world apart. I had a first gen iPad and it made me jones to write — it was intuitive, responsive, fluid. I borrowed a first gen Surface from my work and it’s a beater: spongy keyboard, clunky interface, ugly colors and resolution. It’s been that way from the beginning: clean versus rigid, pleasure versus work. So I won’t let metrics distract me from what matters: a machine/human interface that breeds not beige-box drudgery but joy.
