I appreciate both sets of input here. Thank you!
Both of the computers that I have put Ubuntu on were literally in a drawer, awaiting a trip to the shooting range to be "disposed of." They stopped working well with Windows for whatever reason, and we moved on and bought new machines. Ubuntu has brought two machines that I thought were trash back to life.
We have an HP netbook that runs like a raped ape - it has all the Windows and Office software we use and might need in the future.
So, I'm installing Ubuntu on her machine as I type this message. I will go back and fix the wireless issue (thanks IGF), and then I will go get her preferred browser (Chrome).
Thanks again for the help!
