I forgot to mention that I am running the Windows 8 Release Preview: Build 8400 on my laptop. Internet Explorer 10 is the default browser in that version. If you are running an older version of Windows, you will get an older, compatible version of Internet Explorer when you click on my link. When I click on it, access to IE 10 shows up. Microsoft tailors the IE down link depending upon which version of Windows each person is using.
I just tried to list the most recent "Stable" version of each browser. Google Chrome has 4 separate versions: Stable, Beta, Developer, and Canary. I think Firefox has 3 versions, and Opera only 2. I sometimes make the assumption that others have the same interest in browsers that I do. Evidently, I'm wrong.
You know, if anyone would take the time to look at how much effort the Core Developers went through to produce this theme, you would be impressed. I admire them for what they have accomplished. Don't kick a gift-horse in the mouth. If you don't like the theme: choose another.
Windows XP is over a decade old, and Microsoft has always supported backwards compatibility to retain their corporate and governmental clients. At the same time, they have received loud condemnation from those that wanted them to keep up with the most modern market advances.
Do you want the WordPress Core Developers to always look behind them waiting for their customers to catch up, OR would you prefer that they constantly look towards the future.
I prefer the second choice.
