Last year I took a small netbook to Goa to keep in touch with family on Skype and e-mails. I used Wi-Fi in two places and hey presto, half my contacts started to receive e-mails, allegedly from me, encouraging them to buy the little blue pills.

I'm very wary of using Wi-Fi again so is the answer a dongle? If so, how easy is it to get one and what do they cost?
