1 out of 10 computers are now using OSX.
I wonder how many of those are used in an office/corporate environment though?
I wish my company would finally acknowledge Apple as a contender and give me OSX equivalents to their internal apps.

Tired of flopping in and out of a windows virtual machine.
Probably very few but the business market will be changing considerably over the next decade anyway. We're coming up to a Windows XP -> 7 roll out in my educational institute and I wouldn't be at ALL surprised if it was the last major OS update we do with local installs on beefy desktop PC's. Office apps are transitioning to the cloud (and, by extension, should be easy to install and maintain in a dedicated server setup within an enterprise's back end), bespoke apps are transitioning to internal web sites and specalist software is getting increasingly rare and can usually be run in a virtual machine. Looking... oh, let's say five years down the road from now I can see the several hundred WinTel machines (at £700 a pop) being replaced by solid-state thin clients running a really good web browser and the equivalent of a citrix client, lightweight local apps if there's a good reason to use them and a few heavyweight PC's for creating experiments, big-time number crunching etc. What's currently holding it all back is bandwidth, the tech is available now to do this sort of thing, but as organisations refresh their infastructure this is going to be a natural direction to go.
Edit - It's the same with consumer devices too btw (for those saying 'what will students buy when they graduate?'), the game is changing and Apple are leading that change. The iPad is, in a version 1 kinda way, a glimpse into the future. Most people simply don't NEED the power of a modern laptop and, frankly, modern laptops rarely make good use of that power anyway. Kids going into a four year course this year are likely to graduate into a world of consumer-computing where devices regularly cost £500 or less, are built from the ground up to be lightweight, fast and simple systems and where some (maybe most, depends how quickly mobile broadband really rolls out) of your data is streamed from the cloud. Forget the form factor for a moment, that's more-or-less irrelevant, and just focus on the level of hardware you need to run iOS / Android / Whatever and what that hardware is likely to be able to do five years from now.
Oh, and as one final parting thought, consider this: An iPhone that acts as your personal computer. On the go it's, well, an iPhone. Get home, throw it to a screen via AirPlay and it automatically launches a tablet interface on that screen and either provides an on-screen keyboard / trackpad or links to wireless peripherals. Always-on, constant sync to iTunes in the cloud to backup your data, trivial to share and manage content. If you have another device, say an iPad for use on the sofa, it has the same account, the same data, the same save points in apps so you exit an app on your iPhone and when you resume on the iPad it picks up where you left off. None of that is beyond possibility in the next few years, we're really only lacking the mobile broadband part of the chain.
