Sorry to be a smart arse, but when I wrote that post, I was at work, on a Windows 7 box, running Firefox.

I checked just now on my G5, Safari will underline my spelling mistakes.
Also, I'd like to offer my 2 cents regarding updating OS's:
I work in IT, generally, for businesses (running Windows), we don't often upgrade the OS of a PC once it's been sold. They generally run the same OS for the 3 - 5 year life of the PC. sometimes we might upgrade a single unit (say, the CEO's laptop), but not often a whole fleet will get the upgrade, too expensive for licensing. As for the Mac side, again, we generally don't update, unless the OS offers new features that the business needs.
For Apple, the OS cost is lower than Microsoft, but labour is still "expensive". We did some customers from 10.5 to 10.6 (performance boost, also the Magic Trackpad requires 10.6), but most only upgrade when we do rebuilds, or when they get a new machine.
For my personal customers (mostly home users, or 1 - 5 seat businesses), some expressly ask me to upgrade their OS (especially since it's been $60 NZD), but most stay on the OS their mac ships with.
Personally, my work computer always has the latest OS (Work gets MS Licensing), and later this year, I'll get a Mac Mini running ML, and I'll probably keep it updated.
