Well, your choices are limited. Apple used to have a plain Jane Macbook, but now have only the Macbook Air and Macbook Pro - in the States at least. The Macbook Air doesn't have a CD/DVD drive. You'd have to buy an external drive. The Mac Superdrive is $80 US. And for what its worth, the Macbook Air just seems too flimsy to me.
I currently have a 15" Macbook Pro. My first Mac was a Macbook. A client of mine bought it for me as he was sick and tired of hearing me bitch about my Dell. Shortly after he gave it to me, I switched my whole office to Macs and bought a 13" Macbook Pro for my wife. The oldest is about 5 years old and they are all going strong. I sold the my original Macbook to a friend and its still going strong. Every other computer I've owned has crapped out within 2-3 years.
The only complaint I have is that the new OS-X Lion operating system sucks. I never had any crashes until I installed that POS, now all my computers will freeze for no good reason. Until Lion came along, I was huge Apple-phile.
The bottom line, if I were looking for a new laptop, price be damned, it would be another 15" Macbook Pro. From the aluminium case to the components, its is a top notch piece of kit. Its the simple things like the keys not falling out and the peripherals working flawlessly that ALMOST make it worth the extra $$. The fact that it USED to connect, and stay connected, to the internet and other external devices without need for a computer science degree to make it work, was the other value point for me. But, alas, Lion sucks. It was an "upgrade" without a reason - except to sell more product and shit can Mobile Me in favor of the less powerful Cloud POS. However, if I were looking for a laptop to do the things your mom wants to do, I'd keep it simple and buy her a reasonably priced, HP, Sony, Toshiba, Compaq or whatever. I say that because until Apple gets Lion sorted out, its no better than Windows - so the value of not pulling your hair out just isn't there to justify the added cost. You could probably buy two of the above mentioned brands for the price of an Apple. That's just not worth it for a home application to me. YMMV.
Edit: Wow, you guys are quick.
