Mine fell out of space and time last year, so technically mine is the oldest despite being a production unit. I think I'm the only one with the time travel app, but when I launch it, it says Im out of plutonium.
I hate when that happens. It ain't cheap to run my centrifuge.
i pre-ordered mine as soon as it was available to, but since i live in Australia, it took some time for me to receive it.. getting another in a few wks for my fiancee.
