I love what you can plug into your computer today. USB ports have made my life so much easier. First it was just downloading photos from my camera, then I pluged in a scanner, wow! no cards! Then I had to take some file to a friend nd I bought a pen drive [flash,thumb are names also used for this]. I was scared I'd lose it [it's smaller then my pocket knife!] Well I was hooked. then I discovered wireless USB plug ins that were no bigger than my pen drive. this may not sound like much to get excited about, but now when a friend brings over his computer to be worked on... la, la ..internet connection!! Well backups were a little to much for my pen drive, so I invested in a portable hard drive. You guessed it. 4GB that plugs in to a USB & its no bigger than a cigarette lighter. My next project is get one of those new shoebox computers![if you have one up and running-would love to hear from you]!!
