The Microsoft digital distribution store that will come with Win8 isn't the only bad thing about this OS.
I've watched a preview video on youtube where a guy tries out Win8 on his desktop PC,and he showed that the way you control things in it is like iOS or something. It's basically an OS made with touchscreens in mind,not mice. And thus instead of windows having the usual buttons like -,the rectangular and X,to close,minimize etc,you have to replicate the gestures you would do in a touchscreen with your mouse pointer/arrow instead your finger,which makes it just awkward and confusing. But even though if you watch a tutorial and memorize what gestures do what, what it ultimately does is adding extra steps to the procedures someone could do easier and faster. That's not a good point really.
The other thing I noticed is that Win8 lacks features that would make me want to buy it. I mean I haven't learned of any thing that I can only do with Win8 and not with another Windows version yet. Windows 7 was a worthy upgrade as it supports things past versions don't,like SSD trim, directX 11,etc. Win8 is only trying to sell because of its GUI,which is a hit or miss,and personally I don't like the new GUI. Even if I liked it though,there's plenty of GUI customization options available for Win7,which means you can really make them look quite like you would like,if you use some third party software. Win 8 lacks selling points for me.
The last but not least thing I don't like is that they took already known old apps and functions and placed them elsewhere. So to do in Win8 a function that I know how to do in Win7, I will need to spend time to re-learn how to do it. Which I don't like,it will slow my workflow. Why to have to learn a new way to do things I already know how to do them ?
