Hi Michelle,

I think you're better off answering this question yourself.

Just get it running on your PC/Laptop and decide for yourself what the answers would be:-)

Personally, I have been running it and I still have not formed opinions of my own because I use Windows to do certain things and Windows 8 Dev Preview does those things.

I have seen some deep analysis of Windows 8 from folks at TechRepublic (and I strongly advise you subscribe to certain articles from this site) which I believe would help enlighten you. 

I found it quite easy to install and run Windows 8 along with Windows 7 by dual-booting them.

Here is a method I found to be the easiest - http://sharpfellows.com/post/Fully-automated-VHD-install-of-Windows-8-Developer-Preview-using-PowerShell.aspx  - to achieve that once you have downloaded the image of your choice from http://msdn.microsoft.com/en-us/windows/apps/br229516
