What do you all do with your old iMacs, Mac minis, mbps, etc.? I typically trade them in, and was going to do so with my iMac from 2006, which is certainly functional, however, I wonder if it makes sense to work with two computers? Does anyone find that useful, or too unaesthetic? Funny, I offered my iMac 2006 to the kids, but they prefer their MacBook airs. They're only 8 and 9, so I don't think they have a sense of what a desktop really is!! They're certainly utilizing those airs for virtual school!
