Some new stuff on the Windows 8 blog, nothing big though so wont bother adding it to my original post, but it's interesting...
Enabling accessibility - This is about new features to help people with disabilities like visual, mobility and hearing impairments (
vid here).
Reliably measuring browser performance - Shows the testing MS they do with IE, using the IE Performance Lab.
Stuff worth mentioning...
The lab contains 120 machines from desktops, laptops, netbooks to touch devices, both x86/64 and ARM.
The lab measures performance of Internet Explorer 200 times daily, collecting over 5.7 million measurements and 480GB of runtime data each day

The servers they use are each 16 core + 16GB RAM.
Activity is measured with 100 nanosecond resolution.
And...
Since the lab runs 24/7, hardware failures are inevitable. Replacing failed components with identical parts from a different manufacturing lot almost always results in the repaired computer running faster than the other machines in the pool. While this difference would be unnoticeable in the real world, when you’re measuring down to 100 nanoseconds, even a few cycles can impact the results! If after a repair a machine no longer runs identically to the rest of the pool, it is removed from the lab and the pool’s size permanently shrinks.
...Well it's paying off, i noticed with the Dev Preview that IE10 is faster/smoother than any other browser (i do web design so use loads of browsers, but it wont really show if you're running Win 8 virtualized), being as MS deal with real world performance, not benchmark scores!
Some of it seems to be down to GPU, as even text and static images are GPU accelerated. IE9 also had this (and is still the only browser with
full GPU acceleration) but it's improved with IE10. An example of how much full GPU acceleration can impact overall experience is to go to Google Maps, make browser full screen, then drag the map around - it should be smoother on IE9. It's the same with any sites that use HTML5 / JavaScript animations, or even just scrolling up and down a complex page. I'm sure IE10 will be speedy and butter smooth on touch screens... Now if only it will have better add-on support...
