What backpack should I buy?

Some backpacks are specifically designed to carry certain items. Common examples include backpacks for small, high-value items such as laptop computers and cameras (see photo). It is also possible to buy "picnic basket" backpacks that come with plastic dishes and utensils, a tablecloth, etc. Hydration packs carry water and have a tube connected to them from which the wearer can drink. Backpacks that carry skateboards have also become more popular in the youth culture.
