The computer these days is like a credit card. It is something that you cannot leave the home without. But since the computer is heavy, perhaps it is not a good idea to bring this with you everywhere you go. Yes you can try those palm pilots and Blackberry’s but its size makes it so hard to browse. The only thing to do then will be to get a unit from a computer rental.
To do that, you have to find a company that does rent out computers. You will have an easier time looking for them online rather than flipping through the phone book. Some companies which you can check are ICC, Rent a Computer and Laptop Rent. If it is not available where you are going, better get it before you head down to the airport.
