It’s impossible to imagine a world now in which developers proudly browser-sniff to check that the customer is using the “right” browser on the “right” operating system, while they race to code applications that revolve around non-standard “extensions” thereby locking themselves and their users to one browser because it temporarily has the shiniest proprietary extras. That’s absolutely unthinkable as we approach 2011.¹

A relatively old post (over a year), but I found it the other day. A great way of looking at the browser arms race of today.
