I like how fast Windows 8 Pro loads. It is more nimble and seems to be as good as its predecessor, Windows 7 Pro. There's only one reason why I don't recommend it: the missing Start Button.
I said to a friend recently that once we solve the Start Button issue, I'm ready to recommend Windows 8 Pro. His response was: "Windows 8 still has a Start Button. It is just bigger. Press the Windows key or move the mouse to lower left corner."That's true, but it's so clumsy. Sometimes when on the desktop I can easily get the charms to show with my mouse, and sometimes it takes a few tries.
I get that Microsoft wants to have the same interface for all devices. I even think it's a good strategy! But getting to the Start Page (what replaced the Start Button) has got to be made easier than it currently is. Even making possible a simple shortcut that can be added to the Desktop Quick Access Toolbar would help.
Then I would endorse and recommend Windows 8 Pro.
