You're not the only one. I've never been all that turned on by tabs. I tend to think in instances and just prefer to work that way.
I rather like the tabs...but it took me a long time to get used to 'em.
On the other hand, I *detest* the way XP groups tasks on the task bar by default. That is evil and wrong and should be abolished. It's one of the first things I change when I do a fresh install.
