With Adobe Photoshop and Office already going subscription will W9 be a subscription / Cloud based service or not. I really don't like the idea of subscription based models but it seems that the market is moving inevitably towards that type of business model.
Android seems to survive very well as a Cloud based OS without people having to install it on their phones / tablets - but then depending on your supplier you are highly dependant on their bloat / ad / trial / crap ware so I'm not in favour of OS'es you can't locally install either - local installs mean you can remove all the rubbish and get your system running how you want it to.
Get your Old Windows OS'es ready for running under VM software and get your Linux handbooks out again.
The "Whisper" feature at Redmond says there's a lot of discussion over the next model - hopefully the non subscription faction will win out.
