Usually, Close of Business is our video series, which delivers you the day's top news in two quick minutes. Unfortunately, I'm stuck in the Denver airport with wifi that makes 3G look fast.

So, I'm going to recap your news using only the alphabet.

Obviously, the top tech story of the day was the string of announcements Apple made today. First, a new version of OS X will be out in Summer 2011. It's called Lion. Here's Apple's preview of the OS. The pitch is that they're integrating the features that have made the (iPhone and iPad) iOS a success and applying that to the desktop.

The other big Apple news -- at least to me -- is that they released a marketplace for desktop software modeled on the popular app store. The Mac App Store seems like a great idea because, let's be honest, I don't even know what software is available for my computers anymore.

Oh, and there are some beautiful new 2.9-pound Macbook Airs that will apparently have 30 days of standby power (though I'm not sure how much that matters).

In non-Apple news, Netflix may offer streaming-only subscriptions within the year. Apparently, they are testing the option now. No word on pricing, but I'd take that option in a second. I watch about 20x the number of things streaming as I do on a disc. Also: remember when Netflix was considered dead in the water? It's trading at over $150 a share, right at its all-time high.

That's your Close of Business. I'll be back with video tomorrow.
