Yes, I think she'd be fine with that.
Have VPC running on wife's iBook for a stats package that was required for her research statistics class. It's a pretty math intensive app (duh) but runs nicely under VPC on her machine, a 14" iBook with 1.25ghz G4 and 256m RAM. It's no speed demon, the same package runs noticebly faster on my work laptop (HP 1.4ghz centrino with XP), but it's more than usable. I think word processing would run fabulous in that setup, especially given the added RAM.
