Sony warns PC customers to wait before upgrading

Sony issued a strong warning to all laptop owners to be patient and wait before upgrading to Windows 10 until it has performed necessary testing and compatibility assessments. For more information, please see:

Very sensible precaution. More manufacturers should do this. My ASUS Vivo Tab is not Windows 10 ready but not a word from ASUS about it one way or the other.

I too am having compatibility issues, while trying to update to Win10. My issue is with the ATI Radeon display driver.
