Everything you say makes sense. Let me rephrase my statement into 2 separate statements then, as I should have initially. 1. Future browser upgrade timelines should not be based on the IE6 fiasco. It's too small a sample size to use as corroborating evidence in these predictions. It may end up being an anomaly. 2. In my own opinion I think the upgrade timeline will grow shorter. I don't have any hard evidence I can cite, it's just my impression as someone who's been involved in web development for the last 12 years or so. The points you mention are all valid, and I'm not saying there won't be new and different pains we'll enjoy ;)
