I do know she'd likely have some more Star Wars tier tech like laser weapons, my question was more along the lines of how quickly do they innovate in the weapons tech department? Like for example the graphics card in your computer can be significantly outdated in less than a decade. I guess what I'm trying to find out is how old should she be? I know you don't need an exact age, but I'm guessing you'd appreciate something narrower than, say, anywhere between 30 and 80 years old, lol.

So let's say there are cooler cyborg arms out there with artificial muscles, more in line with the MGR type design, how long until her buyer went "wow, the new models are way better?" Is her family still alive after all this time? That's where my head's at, in the finer details before I grab the CS and write the story version of all my ramblings.

I would say towards your reference of star wars tech like laser weapons. She is probably last generation. Which means her age would be 30 to 10 years old. 

I think Atlas is just getting out of the stages of Star wars, Avatar, etc... Type of technology and they are advancing past it.
