I installed windows 8 on my Lenovo ideapad P580 and it gave me so many problems.

- Three unrecognized drivers that I had to use Windows 7 drivers instead of the 8 that were not compatible yet.
- Bluetooth was damaged in the upgrade process and now can no longer even be recognized or listed as any type of device
- Antivirus/antispyware software has on more than one occasion conflicted with Windows 8
- Have to use the online profile mode to get full access to everything.

I ended up having to call Lenovo tech support just to make sure it wasn't any clumsy mistake on my end but they had severe issues. Even went through a clean reinstall version of windows 8 and still had issues. I ended up getting a free 3-disk system restore for my laptop and now I'm back on Windows 7.

Windows 8 is not bad, but its not ready yet. I highly recommend waiting for the first service pack at the minimum. Although, its a lot faster on any older computer/laptops that you may want to speed up (boots rather quickly).
