Re: [WIN8] Windows 8 --- What benifits over W7-64? The Desktop is there for legacy purposes. If you remove it, then you literally have WinRT.
Start8's start menu replacement looks exactly like Windows 7. It even has some Aero effects. Freebie Classic Shell is fine though. Seriously, debating the interface at this stage of the game is a waste of time as either of these 2 options will satisfy 99% of the users out there.
Anyway, the purpose of of Windows 8 is not something MS created just so they can sell you an upgrade. Likewise, it is also not just Windows 7 without a start button and replaced with Metro.
Reason for Windows 8 in the first place is that Microsoft is afraid of the term Apple term "post PC" that everybody accepts. All the so-called tech experts say that everybody will be soon be using non-PC devices that uses a mobile OS. Microsoft realized that those specs can actually run Windows. That means people can do real computing on something with mobile hardware.
Hence, Windows 8 is Microsoft's mobile OS meaning that it is capable of running on mobile hardware. With a mobile OS, you expect things like faster boot and longer battery life. Even traditional non-touch screen devices benefit from these types of improvements.
The biggest difference in this new version of Windows is that you get another OS. That is you get x86 WinRT that can run its own apps. Those apps are more commonly known as Metro/Windows 8 apps.
