Android Laptops tend to be much more powerful than their handheld counterparts. Most are classed as hybrids, which basically means the keyboard is detachable so the unit can be used as a tablet device.
Because Android devices have a dedicated store with Apps and games that have been optimised for the operating system, you tend to find that they are very good for gaming on the go. They are also more than competent for office work, browsing the web etc.
Because Android was designed from the ground up for portable devices the battery life is extremely good.
