I would encourage you to consider a Macbook. I just switched to a Macbook Pro 15" and I Love it. The ease of use, the reliability of the Macbook & all the features it comes with (not like windows where everything has to be bought seperately).
Oh Did I mention that I get to use it instead of always scanning for Viruses & crap.

I agree. If your wife is only going to use it to surf the web, email, store bills, and store photos, a MacBook is all you need (you don't need the pro), unless your wife wants a bigger screen. The MacBook has a 13.3" screen and may be a bit small to her, or the 13.3" screen and the MacBook's small size might suit her perfectly.
The main differences (imho) between the MacBook and the MacBook Pro are the screen sizes and the graphics card. The MacBook has an integrated graphics processor, but if your wife isn't going to try to play NWN2 or some FPS on that computer then you'll be fine with an integrated graphics processor.
Oh, and Macs come with iLife which includes iPhoto to help with storing pictures. There are also a crap-load of other programs you can dl for storing photos, too.
If you get a Mac, get a Superdrive, of course, so your wife can burn DVD's with all of those pictures.
But yeah, MacBook is the way to go, I think.
Here's the tech specs on it...

Edit: Oh, and if you're wife's one to be fashionable, a black (or white) MacBook will sit well with her friends, I think.
Edit:
$400 bucks sale going on right now. Everything she will need in it. No need for macbook or stuff like that. Save your money.

Ok, true, this is cheaper than a MacBook, but if your wife is only going to be doing what you said she's going to be doing, then I think she'll have a lot easier and enjoyable of a time using a MacBook. You barely have to worry about viruses, trojans, etc. (Mac OS X is built from an OS made for security, and people just don't make viruses, etc. for Macs), you barely, barely, barely have to worry about crashes or freezes (if ever a program freezes on my Mac, I just force quit it and it closes. I don't have to click "End Task" 10 times before it'll do something.). And I contend that the OS AND computer themselves are just prettier.
Also, the cost issue. You're getting a more powerful computer if you get the MacBook over that Staples thing. That might not be an issue for you, but at the same time you might find that the half-a-Ghz more of processing power will help her get along with her work quicker.
