Earlier quoted context omitted.
> the clicking thing is much slower than tapping That has nothing to do with Macs vs PCs. Everything with a touchpad gives you a tap to click option, and if you didn't spend enough time with a Mac to realize this then you can't really make a fair assessment of the platform in any way other than hostile first impressions.
Defaults are very important in any UI. An OS that prides itself on usability should have the best default.
Anyway, "the clicking thing is much slower than tapping" is just not true if you're used to clicking.
