My several old computers have absolutely no impact on her computer setup.
I have Lion on my 65-lb MacPro because I bought it second hand with Lion 10.7.5 already installed, and I do have an alternative, physically separate internal HD set up as a bootable Snow Leopard 10.6.8 volume.
Mountain Lion does not even run on this machine, but I'm also not fond of its mobile-device-like User Interface. I have no iPad, iPhone or smart phone of any kind, but my wife does have all of the above; she may well like ML.
My wife's computer and mine share no data whatsoever. When there are documents or images to share, we do it through Dropbox or via e-mail.
I'm extremely grateful for your generous and thoughtful input, as well as for MichaelLAX's contributions to this thread.
The 8 GB of RAM are arriving on Tuesday, and I will proceed to install the modules in my wife's Mac mini, back up her drive and install Lion. If she finds that she needs ML later, we'll try that too,
