It seems the focus of this whole thread is to avoid the new Win8 user interface and stay with the familiar Win7 interface. So we have lots of advice on trying to guide people who are not very familiar with managing computers and installing software on how go go backwards with their new Win8 machines. This strikes me as a very poor path to stumble down.
It is as simple as can be to install a shell - like Start8 - on the new computer. Presto - it looks and operates just like a Win7 machine. Total cost - about 5 dollars. Complexity - very simple.
Our Win8 laptop and Win7 desktop look and operate exactly the same.
I did this on the new laptop so I could start doing the work I wanted to do right away without figuring out the new interface.
I also did not want to go through the tutoring process with DW to learn the new interface.
All the discussion about touch screen is IMHO a total red herring. If you don't have or don't want to use touchscreen - don't. Nothing requires touchscreen operation in Win8.
I can't see installing any Linux/Unix variant as a viable option for people who simply want to use their machine and not mess with the gory details.
Anyway - it is take your pick. Go simple and get what you want or go complex - spend money and hopefully end up with the same result.
