We have one computer strictly for all things financial — investments, banking, ordering, etc., and we don’t even access email on that computer. (We’d heard that many compromises and hacks are via email.) The PC where we web surf and get email never sees a credit card number or financial info.
I’ve been think of doing just that for some time now. I’m going to order a small Chromebook today.
One caveat, I won’t use it for online ordering. I’ve had a credit card hacked twice that way. No money lost of course, but a PIA nevertheless.
