About as fun as a corporate, locked-down PC is.

That's what I'm afraid of. I was hoping people would be less likely to completely hose a Mac and therefore there would be a lower need for draconian restrictions.

Operating systems are not 'fun', it's like saying my house is 'fun'. It's what you do on or in the OS that makes it fun.

I've experienced this over the years with Linux. I will from time to time install the latest greatest distro, configure it, work out all the little nagging bugs and then ....

Nothing, it's not fun (unless you think getting your graphics card to work and spending 4 hours doing it is fun), in fact the goal is always to get the OS to the point where I can use it ... for something else.

Certain operating systems are more conducive to 'fun' experiences than others, much like houses.
