Laptops mostly use 2.5 hdds, and desktop computers usually use 3.5 inch hdds. Usually you can't just take 3.5 and put in in a laptop, or take 2.5 and put it on desktop machine, but you can do this easily with a rack. Some external racks have USB support, and better ones can be used for both 3.5 and 2.5, so you can plug any hard drive in any computer. 2.5 hdd can be fitted in small inexpensive racks with USB support that cover the whole disc and then you can carry them in you pocket because it's not much bigger then pack of cigarettes (but you should be careful not to drop them).
Other then that - 2.5 are usually slower and more expensive, but they consume less power. 2.5 should also be more shock resistant, at least in theory.

You can get a laptop HDD convertor -> IDE for about £6 which is extremely useful for fixing laptop software problems. Or if you just have a spare LP-HDD around

I've plugged my laptop 2.5" hdd into a desktop before using an eSata cable and the generic power supply. As long as the plugs match (power+cable) up the only issue that you should be worried about is size.

These portable hard drives usually have a smaller capacity, 160GB to 320GB is common, but more expensive models already have 500GB and bigger drives. Memory chip based drives called SSD are also available both for notebooks and desktop computers. These drives are way more expensive than a normal mechanical unit, but there are pros to them as well. They have no moving parts, for one, and that can significantly lowers power consumption. The technology used allows faster data access that makes reading of small scattered files faster by the magnitude. Read and write speeds on the long run also rival normal hard drives so they're expected to take their place as soon as the price drops to an acceptable level.
