It works on my VERY old computer, should be fine.
decided to see if the 64 bit version will run on windows anyway. if not maybe I can download an older version.
Fully offline should be OK.
I personally use a brainwallet with a very long and personally unique passphrase.
I would do that but I would have trouble remembering the passphrase, and I want to have access to my bitcoin while still keeping them relatively secure.
I'm not wealthy anyways, I don't see my wallet ever having more than a couple grand in value, and that's when I'm all baller (for me).
