I had an old Vivitar Vivicam 2755 sitting in a closet and decided to poke around with it. Man, how technology has improved!
The Vivicam 2755 debuted around the turn of the millenium. Its features are 640 x 480 pictures (today's digital cameras do much better) and support for both USB and the ability to plug in to a TV to look at your pictures digitally that way. It also has a 1.8" LCD screen and a self-timer function.
It also uses an older-style memory card that is no longer used today. It takes four AA batteries and seems to eat them up easily.
If you are a deal-hunter, you can do much better. However, if you are looking to give your child a cheap digital camera you found at the thrift shop, this might be the ticket for a budding seven year old photographer. Even then, it is my understanding that there are troubles finding computer drivers for this to work on Windows XP (says the result of a Google search).
The Vivitar Vivicam 2755 was a good camera for its time, no doubt, but new technology has passed this generation of digital cameras into obsolence.
