I’m a “just in case” packer, so I know that having a big backpack means I’ll find some way to fill it up. If you’re a pack rat like me, it’s time to trade in the heavy bag for something that’s smaller and lighter.

A cheap notebook may sound like a contradiction in terms - after all, just a couple years ago, notebook computers retailed for about two thousand pounds, and it was difficult to find a good product for less. That situation has changed - refurbished laptops are an affordable choice, and often just as reliable as a new systems. These cheaper laptops might have been previously used, but if their hardware is in good condition, they can be made to easily run up to date software. Amazingly, some of systems sell for as little as three to five hundred pounds. It is possible to find cheap laptops!

Two common types of built-in laptop hardware serve the same purpose as a separate, moveable mouse or trackball:

• Touchpad: A pressure-sensitive rectangle that sits in front of the spacebar. The onscreen insertion point or selection point moves in response to the movement of your finger on the pad: up, down, left, or right. The touchpad is, obviously, much smaller than the full LCD screen; this may mean that you have to slide your finger across the pad several times to get to the top or bottom, left or right of the image. Figure 1 shows a typical touchpad.

• Stick or pointer: Usually embedded in the keyboard and extending slightly above the height of surrounding keys. Software interprets the push of your finger (and the amount of pressure applied) to move the cursor at varying rates of speed.

Under both designs - touchpad and stick - you also find a pair of action buttons nearby. The buttons are the equivalent of the left or right mouse buttons and are used to issue commands, make selections, or call up context-sensitive menus. Most touchpad designs also permit an alternate means of communicating the pressing of a mouse button; a double tap of the touchpad with the finger can be interpreted as a left mouse click.
