Not if you're running Windows 7.

If you're running XP or Vista and you're happy with that, then you probably don't care very much about which browser you're using.

Interesting view. I certainly care about what browser I use on my XP installation. I (and my coworkers) have always cared which browser we use. But, we aren't Web 2.0.

Sure, some people who are trapped in XP at work might care, but do you really care that you don't get IE10?

You still have decent browsers to choose from (Firefox, Opera and older versions of Chrome if you can find them).

To better explain my point - if you care about which browser you're using, you're probably not pining for IE.
