Do you use Windows 8?

I have been using Windows 8 since the last week of the developer's preview, and overall I consider it to be very impressive. The only time I have booted into Windows 7 was once last week to get my Office product key in order to install it on Windows 8. I had been using it on a desktop with 1024x1280 resolution and had not been able to use snap, but today I installed it on a 5 year old Inspiron 1525 laptop with a 1050x1680 display and it has been working beautifully. People have been saying that Windows 8 is too focused upon touchscreen devices, but I have not used it on a touchscreen display yet and I still use it as my daily driver. So, to cut to the chase, I was wondering:

1. Have you used Windows 8? If so, how long, and if not, what is keeping you from it? (The rest of the questions are focused upon people who have used Windows 8.)

2. What devices have you used Windows 8 on? Tablet, laptop, desktop, et cetera?

3. What are your experiences with the OS as a whole? Do you think it is a quality product? Have you had any problems with it?

Hopefully this leads to an insightful look at how people have been using Windows 8.
