That's because most computer users fit into one of two groups.

- Those that haven't tried Macs.
- Those that have tried Macs and now use them.

The second group are clearly a small minority, although unsurprisingly are well-represented in the affluent, computer-literate place that is FT.

There really aren't that many people who have knowledge and experience on both but prefer PCs. Most PC users I know who are also Mac literate use PCs because for compatibility with work systems, cost reasons, etc. Not usually because they prefer them.
