Just wanted to see what the collectors on Macrumors find the most valuable in their collection, sentimental or not. If my screen name isn't a good indication of what MY favorite collected computer is, then, well I give up . The reason the Quadra 840av is my favorite collectible apple has more to do with sentimental value then cash value. I first used the 840s back in High school when they were new. If you were in the Video Production program at my high school, you were given the username and password to log into one of the many Video hardware equipped Apple computers. You were also aloud to "play" on them during any study hall or other free time you had in school. I had completed many projects on the Quadra computer, including an end of the year video back in 1994. That Video was played in front of most of my Sophomore class to kick off summer. that was also the only time I have EVER used Rap in a video. In the 2 years we had the Quadra (they GAVE it to the Middle School for the 1994 - 1995 year) I had learned how to use the Speech recognition features, and the Quadra had "learned" my voice well enough for me to do much of my work by using only the mouse and my voice . I currently still use my Quadra to digitize audio from Cassette tape, and in about a month, I will be digitizing vinyl records from my Mom's collection, so she can listen to them on her iPod. I know my G5 can do everything my Quadra can, and much faster, but there is something about the Quadra that makes it more fun. Please share your stories in regards to your favorite Macintosh.
