My desk
Last year I bought myself a laptop. For years I had had a desktop computer, but I decided I needed something smaller and more portable. I love it. At home, I use it with a wireless mouse as moving the arrow around the screen with the touchpad is tricky. It took a while to get used to the position of the keyboard because it is so close to the screen, but I managed. I log on to the Internet every day to check and send emails and spend about an hour a day online, surfing the Web. On my desk, I also have a scanner, which I use to copy pictures and documents. And of course a colour printer, which I use when I need to see documents and pictures on paper.
