An event horizon is the part of a black hole where the black hole actually has enough gravitational force to pull in light. Thus the name, it's a black hole, well cause light gets sucked in and you can't see it anymore.
Windows 7 is coming, you don't even have to put your ear to the ground to hear this one, it's everywhere, it's saturated, and well to me - it doesn't mean anything.
I'm a fan of new technology, in fact I'm writing this on a PC that's running a beta copy of Windows 7. I'm a fan of pretty much every modern OS, to me, they all do the same thing these days. I'm hard pressed to think of one thing I can't do across multiple platforms. I know each major player has their share of fans. For me, it's Windows, if I was forced in to running OS X or X Windows tomorrow though, I wouldn't really freak out. I could pickup pretty much everything I do now and keep on trucking with it. I know people use different applications for work, depending upon the industry you work in, the software that's native for you at work, has a better chance of showing up on your home desktop. This is a benefit to Microsoft and PC OEMs, however the enterprise implementation of new technology is always slow. It's the nature of the beast, the almighty bottom line will hinder new technology adaption, unless that new technology can offer some great feature that will in the long run cover it's cost of implementation and in turn increase profits.
We all know what I'm talking about here, Windows XP works, it works fine. Just as I can go cross platform, I can probably go from Windows 7, Windows Vista, Windows XP and Windows 2000 without much of a problem. (I recently tested using Windows 3.11 on a modern internet here)
Operating system innovation has in some ways hit a wall. Sure, touch devices are a big thing, and they're fun, there's more than a laundry list of features and time saving additions to new versions of operating system software. Though at the end of the day I don't really say, "thank goodness I'm on this version of Windows", I don't see much difference.
Has the feature list hit the Windows 7 Event Horizon?
