I'm from NZ and even I laughed
You could also add that some are defective....you only have to see that show "The GC" to know why I say that.

With a bit of FreeBSD scattered all the way through, I've always had a soft spot for it.
I ended up with Ubuntu in the end because it was less hassle to maintain (I want a system that's quick to build and I can spend more time using it than configuring or maintaining it) and had relatively up to date packages in the standard repo's. I no longer have as much free time or am as enthusiastic as I once was, performing stage 1 installs of Gentoo in the earlier days.
Horrendous cost aside, where I live (and I'm betting a lot of other places), you can't have multiple devices on the same data plan.
Why can't you have a 3GB plan shared by your 3G phone, 3G tablet and 3G enabled laptop? You're the same person, they're all your devices and your usage varies between the 3, but they want you to instead buy 3 separate smaller plans which total up to a lot more money for the same amount of data.
Sort that out and maybe I'd start considering 3G important in other devices. In the meantime I'll tether. Slightly less convenient, but a hell of a lot cheaper.
