I have no interest in IE11 etc...,not used it as my main browser since IE3 so shows you how long ago that was.
Big question is what new features will Windows Blue have and will pricing be good value for money ,enough so that Win7/8 users will think about upgrading to Blue.
Also will anti-Metro fans on Win7 etc be swayed by the improvements in Blue's Metro etc....
Guess only time will tell.
