He meant, you can click anywhere in the window and use Alt. If you left-click, it moves the window. If you middle-click it (apparently - I did not know this) will resize the window.

Mac OS X has oddly small targets for many of the Window management things. You have to be careful with the mouse when finding a resize corner (Lion makes it a little better) and the traffic light buttons are such a frustration that I'm led to believe they are not really meant to be used in an efficient work flow. You're better off enabling double-click-to-minimize or using Cmd-H to make a window go away.

There's now a full-screen mode that takes care of that. But that green button is still there and still behaves strangely. It's funnily called the zoom button. Naturally when you click it in iTunes you expect the iTunes window to.... shrink down to a compact size. I know the purpose of it is to 'change the window size to fit the content' - a nice concept but doesn't seem intuitive or easy to grasp for everyone.

Darwin ports? Fink?

Haha. I tried to get rdiff-backup or duplicity installed using MacPorts on Lion - it started by trying to install python2.4. And failed.

Anyway, this is not much of problem with Mac OS X - but despite being a Unixy system, I found it odd that certain tools are actually easier to run on Windows that on a Mac (not all but some)

Overall I like Mac OS X - it has great boot/shut down/sleep times, it can run a bash prompt as well as Photoshop and Word. But I'm skeptical about its usability being, on the whole, better than a Windows 7 system.

It's better in certain ways but worse in others.
