From windows 8 to 8.1 to 8.1.1, i have installed all three major versions and used as my main OS for about a week or two but i end up back at windows 7 after that. And appreciate the 7 even more every time.
-I still don't get what microsoft is trying to do with those apps. They just make OS messy and i never use them. So i loose the cleaner feel of windows 7 here.
-Aero is gone because it's "resource hungry" now. What about back in 2007 when vista came out?? These days most PCs are more than capable of running Aero anyway so it's very lame excuse to take it out.
-"Devices and Drives" are together in My Computer (This PC) now which is a big mess. Windows 7's separate groups for "Hard Drives" and "Devices with removeable storage" is much more organized way to group.
-"Details Pane" is moved from bottom to right side. Another mess up. It takes up your precious work space now. While in bottom it doesn't get in your way.
-Ribbon interface is also not necessarily an improvement over 7's style. It occupies space if you keep it visible and if you keep it minimized, you'll need to deal with more clicks to get the job done.
-There are talks about under the hood improvements. But on my PC , 7 feels just as fast as 8 or may be even a little faster at times. So those improvements aren't doing much here either. It just feels like 7 makes better use of my hardware.
-Don't wanna get into security debate. Windows 7 still have lots of support years left so it's a non issue.
So basically i am back to 7 again and "8.1.1" is sitting in my "Vmware Workstation 10.0.2" to keep myself in touch with Microsoft's Vision.
Edit: And yeah two things i love about Windows 8 are its new Task Manager, and Copy/Paste interface with advanced options.
