It's very easy, just get back the stupid Start button. Yes, that's what the think tank in Bellevue did. From the leaked images of windows 10, one thing for sure, is that the good old start menu is going to be back and it is going to be awesome with added functionality. Now you can add your favorite apps on the start menu, which is incredibly cool. In case you are interested what's in store from Microsoft head over here...
What else do I want in there? For all the compatible devices please give Windows 10 as a free upgrade rather than selling those student, home, premium crap. On top of that, add the basic Office suite as an inbuilt app and auto backup functionality for all docs with at least 100 gig free online storage in 'the cloud'. Have the same functionality irrespective of the platform, may it be desktop or tablet or phablet or a mere phone.
What else do I want, yes make it open source and let the developers do what they want...
Wait, what am I asking for here... A version of Chrome OS from Microsoft... Crazy me...
