Nice! Win9 will introduse transparent tiles... Something that I have been expecting from the release of Win8. Semi tranparent Metro UI, best invention since the bread!
The win10 is more interesting. It can not be completely Cloud based if it can run winXP, Vista, Win7, Win8, win9 etc. programs. The prediction of somekind of MS-"Crome OS" style OS is more likely. Office and many other smaller programs goes to the Cloud (you can use same programs with your phone, tablet, desktop etc.) but there will be a client that can run programs locally. It kind of makes sense when considering how much information there are in the cloud at this moment. But I will never believe that some big company will put its company secrects to a cloud server that is hosted by another company... There will be local content allso. When considering that so many coverment is spying on internet, some critical information will newer be put in the cloud!
Grain and salt, grain and salt... but these can be true, if we just forget the posibility that win10, will be completelly cloud based! It may actually connect windows, winRT and winP platforms in the cloud level though!
