Once IE7 comes out soon, I wonder if older versions of IE will stay in use? What if we (as designers and developers), made IE7, FireFox, Opera, Safari, or another newer browser a requirement?

All the older versions of IE came with Windows, and in order to get a newer version you had to get a new OS. But IE7 will be downloadable, and thus much easier for people to upgrade. There’s also FireFox of course, which is also downloadable. Sites now require Flash, so why not require a newer browser?

Of course, this would only work if there was a mass boycott of older browsers (ie developers refuse to code for them), and I doubt that would ever happen.
