        IE 9: First look at the new JS Engine

        The IE team is busy working on the next version of the world's
most popular browser. IE 8 is the most widely used browser on Windows.
IE 9 is currently in the oven and the IE team is ready to talk about
what they're working on. Here, JavaScript engine team members John
Montgomery, Steve Lucco and Shanku Niyogi give us an early look at the
new JS engine that will ship with IE 9. As of the interview, it is on
par with the latest performance numbers of the latest Firefox beta and
making progress in catching up to Chrome's latest V8. Again, this is a
really early look at where the JS engine is and where it's going (and
what they've done, architecturally, to speed up IE's JS engine).
Enjoy!

                    Hey Now Charles,
 
This was a very good vid! Really enjoyed it. 
 
Aside from JS improvements in IE9, your statements on the user
experience is important which I'm sure we all agree & sure hope
that there is the feature 'Speed Dial' which could be the best feature
since tabbed browsing. 
 
Thx 4 the info,
Catto

                    @Charles: Complex computation in JS isn't any fun.
I did PNG compression once... it was slow. You had to wait like 10-15
minutes for a file to save. It didn't run in a browser though.

                    I request someone from the IE team to please give
a straight answer right away. Will IE 9 run on Windows XP SP3 and
Windows XP 64-bit SP2? If yes, will the XP version continue to use
GDI? How will DirectWrite and Direct2D for XP be handled bcoz there's
no WDDM! You can't kill support for an OS that 70% of the installed
base use.

                    For the love of God, it's 8 years old. Time to
move to 7.

                    I think it's very unlikely that it will be
supported in XP. It's an OS that's over 8 years old now. You shouldn't
be using it any more.

                    Remember IE9 is still probably 18+ months away.
 The market share figures should be different by then (or at
least Microsoft hopes they will be).  Besides, people who are OK
with sticking with XP are probably OK with sticking with IE8 (or other
browsers).

                    All I want to know is, well we have a proper tab
switching experience? Meaning, can I switch tabs while the
stuff inside a tab is not responding?
 
Can we actually have a default download directory setup as a
string, like Home Page URL? What I mean is, we always have the same
home page until we specifically change it, can we just have the same
dumb easy thing on download directory? I think it is annoying when the
directory keeps changing based on the last download, it is more
complex in code and harder for users to use.
 
Spell Check please, oh man.
 
And I really think they need to change the GUI design to release more
vertical spaces.
