how computers have changed over the last 10 years

10 years ago computers were large and were very slow, and when you would download something it would take hours to download. Over these last 10 years computers have decreased in size and are 15 times faster than they were before. For example dsl allows downloads to take 10 times as little time than before. Also some computers are small enough to fit in your pocket and go faster than those large computers 10 years ago.
