Oh, it's also worth noting that if you do (e) you may well have security issues - basically most things going out from your computer will be unencrypted and things like e-mail passwords are easy to intercept. Consult with a geek about something like VPN, or secure logins, and invest in setting up some firewall software. I think XP's built-in firewall (at least with SP2 or later) is probably "good enough", but you'd have to ask a Windows user.
