@Charles/Dean, thank you for making this Q&A video.
Dean's response to ZippyV's question regarding plugins was insightful. My personal opinion is that the traditional plugin model (for any browser) is a dead end.
I should have been more specific with my question regarding touch. IE9's chrome was the intended target. So thanks Dean, you did the best he could with a open question like that. If I had to reframe the question, it would be around usability testing and ui design philosophy. I could be very wrong, but I don't think the IE9 team does enough testing when it comes to touch. Now many of the same issues (ex. context menus, scaling) affect the rest of Windows as well. I just thought with 60% of PC usage centered around web browsing and the coming wave of slates/tablets that IE would be the precursor (similiar to Office Ribbon or Zune UI) of what eventually will need to be done with Windows v.Next and touch.
The question about webslices rose from the removal (hidden) Feeds icon in the default IE9 Beta chrome. That suggested to me that Microsoft was backing away from this. Sure you can move your mouse over content to see if there are webslices to be had. Though thats not the way I would want to discover content. It will diminish webslice uptake. Maybe there is a better way, so I was glad to see Dean churn for a brief moment on the idea of previewing webslices from a pinned site. I actually think pinned sites are the way to go long term. Possibly leading to removal of the traditional favorites bar, etc... Instead let the act of pinning a site subscribe the user to related RSS feeds and webslices in one shot. To do this, pinned site jumplists would need a way to interface with the IE Feed Store/Sync. An additional user benefit, users wouldn't need a full brower session just to preview updated webslice/rss...providing an enhanced app like experience. I don't pretend to have thought this through (your job IE team) but I believe there are more ways to leverage pinned sites.
Re: Bookmarklets: RoboForm is one of the better ones out there. Personally, I'd get more out of having accellerators listed in an easy to access icon (on the default IE chrome) instead of being accessed through a context popup menu.
