>> Will she even need an Office type program? <<
Oddly, I used Macs last year for the first time in quite a while. I was shocked to find that MS Office ran better on Macs than on Windows. All I can figure is that MS knows it has to compete if it wants to sell Office to Mac users.
Unless you have use for Access (a program which is underused in homes and small businesses), OpenOffice is comparable to MS Office... but it’s available for free! (openoffice.com)
The Mac Office developers have pride in their work and have a standing challenge to always do better than the Windows Office developers. They'are a tiny enclave in the huge Microsoft, so they have something to prove.
