Should I download Windows 8 on my HP laptop?
Personally, I would not bother unless there is some very specific feature that you need. Sometimes I just stick to Windows XP.
No. It is meant only for phones and Surfaces as well as the surface of your Surface.
download yes install maybe i would try a dual boot to see if you like it
It depends on the specification of your HP. If ur computer is good on Windows 7, then it's not bad idea to try 8. I like 8.
