Suggestions:


1. In glorious England, internet is free in any public library.
   You do not even need a laptop.
   Just ask the librarian for an internet access code.
   If there is a queue for the net, then internet cafe is the answer.
   It is very cheap, much better than having your own computer.
   Connection speed is faster too.
