This isn't just a 'free product'; it's an interface to a service that they make considerable money through.

After years of being derided as a games-less platform, Valve finally brings Steam to the Mac – but does it pretty half-assedly. I know a half-dozen developers who could have done a better interface than this.

I don't mean to sound ungrateful, and it's better to have it than not, but with the effort I'm sure it took to port the whole thing over to the Mac, I'm surprised that the little things (like copy/paste) don't work.

It's great that they're treating the Mac like a respectable platform, but this is going to be a terrible introduction to any Mac users who've never used Steam. My first impression was 'It's slow, it doesn't work properly, it won't download Portal at all, and the demos it downloads don't work.' Not exactly high praise.
