Custom Notebook Design

- Netbook: A smaller, lighter, more portable laptop. It is also usually cheaper than a full-size laptop, but has fewer features and less computing power. Smaller keyboards can be more difficult to operate. There is no sharp line of demarcation between netbooks and inexpensive small laptops; some 11.6" models are marketed as netbooks.
- Ultra-thin Laptop: A newer class of laptops which are very thin and light.
- Tablet PC: these have touch screens. There are "convertible tablets" with a full keyboard where the screen rotates to be used atop the keyboard, and "slate" form-factor machines which are usually touch-screen only (although a few older models feature very small keyboards along the sides of the screen.)
- Rugged: Engineered to operate in tough conditions (mechanical shocks, extreme temperatures, wet and dusty environments).
