Right at this moment, big changes have or are about to occur in three well-known browsers: Internet Explorer is finally being updated, with version 7 in its third beta and almost ready to roll out the door; Firefox is also ripening an upgrade beta for its Version 2.0—it's in beta 1; and finally Opera, which has a devoted but smaller following, has recently come out with Version 9.0.

So, three new browsers in the same year, after no action for a half decade. How do they stack up? We do a comparison of features, usability, memory, and disk usage to help you decide which you should spend your hard earned…oh wait a minute, they're all free, so you can pick the one you want without worrying about out of pocket. Keep in mind: We're just looking at what's there right now, and not considering what the browser developers may have planned for later additions. Also, these are such feature-rich apps that it would be impossible to compare every little detail—which has support for Atom feeds or importing OPML, and advanced Java settings, for example—we'll stick to the stuff that's most apparent to regular users. Let's take the browsers out for a spin, then, shall we?
