So, IE7 is going to have tabbed browsing. I’m not going to get snarky and ask where they were 5 years ago; they considered them and decided not to implement them for what, I’m sure, seemed like good reasons.
I am, however, going to ask: How do you think MS will clutter up and make more complicated the already-established experience of tabbed browsing?
MS has a history of installing new features that are already popular in other places, but trying to make them such a complicated fusion of user-friendly and overly-robust that they turn into a half-useful mess (IE’s new popup blocker is my favorite example).
