I installed Windows 8 on a virtual machine. Yeah, I used it for ordinary work: email, work apps, general internet use; the experience was different from my Windows 7 experience. The metro UI did get in my way. I also found myself missing the start button. I worked entirely in desktop mode. I didn't use the metro apps because I wasn't using a tablet or smartphone.There is a reason I still use a laptop and desktop because I don't like doing my computer work on my smartpone or tablet; so why use the metro interface?

I did like the change in windows explorer and the task manager, but those two things won't sell me for personal use nor will those things influence my recommending anyone, personally or professionally, to purchase the upgrade. I would stay in desktop mode always, so why upgrade?

If I do upgrade I will wait for SP 1.
