Microsoft is another step away from it's money-printing all-consuming behavior (i think so). Here is what you get in 2015.
Windows 10, free to update:
Windows 10 will be a free update, for users running Windows 7 to Windows 8.1 on PCs or notebooks, and for Windows Phone 8.1 users on mobile.
It's Spartaaaaaa...n:
A new browser is coming, called Spartan with reading and PDF markup mode built-in.
Windows 10 mobile ecosystem:
Windows 10 mobile now syncs with desktop, tablet and many other devices.
Free Office Suite for Wondows mobile:
I hoped for something better ! .... and Office 2016 will be released in 2015.
Microsoft HoloLens?
Hmm, now this is new. This is an 'Augmented Reality' device extending Windows 10.
