Keeping up with technology after 50

I am sure lots of people after 50 are very technical savvy on computers. I am not one of them. I have only purchased three lap tops in my life time and two of them were purchased Saturday. After  my destroying my husband's desk top computer I was in desperate need of a computer. My laptop was not working so I decide to purchase a new one. I went to the store and saw this cute red one. It was small and light. After making my purchase I did not have any problem and I was up and running. The problem started when I wanted to insert a CD that I just purchase and realized that the computer did not have a place to insert my CD. I finally realize my cut little red computer did not have what I needed. So I took it back to the store and purchase a bigger and not so cute computer. I guess looks are not everything when it comes to buying a computer
