Oldest computer and/or accessory/gadget that you're still actively using?

My 2006 white Macbook still gets very regular use.

I very recently retired an old Linksys router that I had been using for about ten years for an Airport Extreme.

My fall back Iphone 3g, everytime I went to go get the 5 something came up more important that required my iphone 5 money. its so late now in the cycle I might as well wait for the 5S.

I inherited an old TI Datamath calculator from my dad. Vintage 1973 or so from what I've been able to determine. Sometimes I use it when I feel like just reaching over and sliding a switch instead of opening the calculator on the computer.

I also have an alarm clock that's of a similar vintage. Stole it from a friend's house in second grade.
