So I get why you'd want to run Tor, TAILS, Electrum off of a USB stick... but on the other hand, those seem fairly easy to lose, etc. I guess maybe the only concern would be related to BTC wallets (Electrum/Multibit) but without a password would they be useless? I guess bookmarked onion sites could also pose an issue...but prob only w/LE. Anyhow, just something I was thinking about, I'm clearly a tech idiot so have at me if you feel so compelled.
Just keep it in your purse
