[dba-Tech] Windows 8

Windows 8 to buy or not.

I have had a copy of the Beta version of Windows 8, running off a virtual
drive, for a while and was wondering what to do next. So far none of my
clients or friends have indicated the slightest interest in moving towards
the OS, in fact quite the opposite.

Now I have been receiving a steady supply of emails from Microsoft saying
there is still a chance to buy a $39.00 full Windows 8 Pro package before
the January 31st deadline when the product goes up to it $249+ price.

It seem worthy of getting it as it also offers six months of free music
downloads, to sweeten the deal.

The question I am having is how the install works...it calls it an update
and appears that the package is so designed that it will over-right the
current system(?) I would not mind just downloading the package and putting
it on a DVD or portable hard drive for later use but I have no idea how this
upgrade works. I have no interest in using up a computer just for a testbed
at this point...a virtual drive would be acceptable though.

Years of working with upgrades have made me suspect of any product claims.
Has anyone else done this process? What are the results?
