It is an intriguing technology, and I certainly do like gadgets. But so far I just haven't found a good enough reason to actually buy one yet.
Actually I have been playing around with my little lathe lately, and have gotten stymied twice now because it just wasn't big enough to do what I tried to push it to do. So toying with the idea of getting a bigger one. But "bigger" means "heavier", and that is getting to be more and more of a roadblock for me as I get older.
But having tools that give you the ability to actually MAKE things is really rewarding and satisfying.
Now if someone would come up with a Star Trek replicator, I would be all over something like that. And whip me up a transporter while you are at it, please.
