One of my first columns was about Mac vs PC. At the time, about four years ago, I wrote about how Macs had changed and weren't really Macs anymore. That they were PCs inside an apple peel. And how it was all about the software. How much has changed - and how little.
The share of Macs in the market has rocketed up. Not because they've gotten a lot better, nor because PCs have gotten worse. The prices for both are closer now and Windows 7 has fixed many of the complaints that people have had about Windows over the years. So, what's changed? What we carry in our pocket.
