Well, by that standard Operas design team must be the best of the bunch, seeing that most of the features modern browsers spout today (with the expection of addons, to which opera came notably late. But the big O had most of the common addon features built-in and managed to stay fast and slim, so make of that what you will...) were first developed/implemented by Opera and then subsequently copied by addon-makers for other browsers or directly by the various browser devs...Greg Tito said:[...]and the moveable tabs lining the top of the screen are just as convenient as they were when I first downloaded it. How good is Chrome's design? Well, if both IE and Firefox are aping it, then the Google Chrome team must be on to something.[...]
Edit: That's what you get for assuming almost noone uses opera on here. I see the norwegian ninjas already educated about feature timelines
Edit 2: To bring something to the discussion: One of the foremost reasons why IE retains such a large market share is the simple fact that other browsers don't offer (up to date) MSI packets for easy remote deployment. This is an absolute killer for most admins, especially since Chrome and FireFox have taken to racing each other with their update schedules.
Try to update every browser in an 500+-company-structure by hand, on a 6-weekly basis or whatever the current schedule is. Just not doable.
Hell, it's hard enough for me to do in a 50-head-company, and the only reason I do it is because I absolutely despise IE in all its forms and iterations.
