So, some good feedback in there - pinning tiles to the desktop is perhaps a good idea if implemented appropriately.
Browser wars clearly abounds. Most of the world still uses IE of course, but despite the 'waaah IE sucks' attitude that seems to prevail so strongly, Microsoft /have/ been making steady improvements to IE over the last few years, and the reality is that it works just fine.
/IF/ Microsoft wanted to switch to something different (and they don't) then they wouldn't necessarily need to do a deal with Google, they could just do exactly what Google did, and grab themselves a slice of Webkit, ditch the Trident rendering engine and replace it.
This isn't going to happen of course, despite feedback, certain things are still 'red lines' and won't be changed. Feedback on the general functionality of Windows 10 (and bug reports) is one thing - asking for fundamental strategy shifts is quite another.
Don't forget, Microsoft /is/ making strategy shifts. Given how many of Microsoft services are now available on rival platforms (You can get OneNote on Android watch, Office on an iPad etc), I really don't think anyone can accuse them of being the 'bad old Microsoft' of years gone by. Not saying they're perfect - but they're different, in a good way, and should be applauded for the approach they're taking in Windows 10.
