Apple laptops aren't the sturdies of machines, neither the most practical.
I'm really happy with my Macbook Pro, and have it with me all day. But I'm being really careful when handling it, simply because it would be such a shame to dent it. Thank god, six months have passed and the only damage is a scratch on the bottom in the anodization.
If you take care of it, you'll be fine.
However, I used to (before switching) buy IBM laptops. These were both for work and personal use.
The IBM laptop (I used the T-series only) is propably the most well-made laptop ever, in a sense that it can stand being man-handled each and every day.
There are several reasons for this:
- The IBM it built up around an internal frame, with plastic and rubber panels (on the back of the screen) on the outside. This flexes more (where it should, intentionally) when the laptop hits something in ie. a drop, letting the panels take the punishment so your components stay safe. This is unlike the Macbook/Pro, that has an exoskeleton. While this is very stiff, all the components are boltet on to this external frame - so if dropped, there is no flex. It will dent, and all the internals will take punishment.
- The Harddrive is mounted in suspension, keeping your data safe should you drop the laptop. It has the same motionsensor as the mac, but if the force is hard enough this won't matter - the suspension will be more efficient.
- The materials used are more practical. Scratches won't show, they are more resistent and dont discolour.
I'm not trying to sell you anything, even though it may seem so
I love my mac, but if you want to take your laptop to hell with you, go for an IBM

You won't get a more sturdy and practical machine. Only thing is.. it doesn't run OSX
This post may seem out of line, just wanted to write about my apreciation for this trusty machine. End of line, you should be fine with the Macbook Pro, as long as you take good care of it. Like mentioned before, I have it with me all day in a backpack with no problems.
