[citation][nom]back_by_demand[/nom]Surely the thing that us the end user wants is a single cohesive system where everything works with everything else - a document created on Surface RT, syncs with skydrive, opens on my PC, edits it and syncs with Skydrive again, open it on my phone - if anyone was for being less integrated and wanting division then they should go because it is not what is in the customers best interests...[/citation]
You are missing a few key points here. First of all, one the great things about windows is that you should be able to sync with WHATEVER you want. Not just skydrive. So parts of the OS should be open to other methods of syncing (not sure if that's possible, haven't tried).
The BIGGEST point to make isn't how the software is compatible with other devices (tablets, phones), because that part of it is genius. The BIGGEST problem is that they expect 1 GUI to work for all devices as well (phone's excluded). You simply cannot make 1 method of doing things and expect it to work flawlessly with multiple methods of controlling the OS. We've seen countless times that Keyboard/Mouse-centric GUIs don't really work for touch, and using a KBM setup with a Touch-centric GUI is both cumbersome and a waste of screen space. If they wanted real integration, they should have built-in the ability to adapt the UI for the method used to control the OS.
Another enormous oversight is the way they handled Metro (sorry, we'll always call it that). You can't claim to have cohesion while simultaneously tearing the OS in half. Metro has a taskbar, the "classic Win7" side has a traditional taskbar. Why is there two!? In order to see ALL the programs that are running, you can't just look at THE taskbar, you have to look at TWO. In fact, if you're in the metro interface, you have to launch the desktop just to see what's running in the taskbar! That is the very opposite of integration. They dangle that word like it's a huge new achievement until you try the OS out and find the reality contradicts the rhetoric.
Win8 has entirely failed to accomplish its goals. They've split the OS in two and they've ruined the user experience for the majority of users (KBM being most popular still).
