Actually as someone who works for a company of 7,200 clients that are 95%-ish female and the other three employees i work with are female, gender is something I think about.
Which is why you see me write "he or she" quite often.
As to the question raised, I just save everything that I download to an external hard drive and would just install it off of that to any new computer.
Dr_Worm: Having a home file server is nice, I have all of my GOG games downloaded to it so I just have to run the installers from my network. (My GOG folder is about 1.33 TB in case you're wondering)
I've thought about doing that at the office but discovered that most of my external hard drives are hardware protected in some manner and I can't just pop the plastic covers and stick them into a server case. I'd have to start over again with new hardware.
