Basic white plastic macbook would be all you need. Easy to use, plenty of battery life, and overkill for everything you'll be doing. Office is available and works well on a mac, and with the macbook you won't have to worry about viruses or spyware (at least not as much as on a pc). They're simple enough that you won't have to waste alot of time getting everything set up and working, and everything is really easy. You wouldn't have to worry about as much stuff as with a windows laptop.
That said, just about any basic laptop, windows or mac, will suit your needs. If you have the budget and are willing to spend it I think the macbook would be more suited to your needs.
Maybe look around, find something that looks good and post the specs on here?
If you're going to do that then make sure you give us RAM, processor type and speed, and hard drive size.
Other than that, 2GB RAM would be good, and you'll probably want at least and 80 GB hard drive.
