Today, I sent an SMS containing a Haiku Poem. It read as follows:
B4 its 2 l8
i c u l8r
2nyt k?
The person I sent the message then sent a message back converting my Haiku into proper English, as follows:
Before it is to late,
I will see you later,
Is tonight ok?

E-mail is a better communication service due to it being a free service and it is easy to write in language that everyone understand and you are also not restricted to how much space you use. It is also more efficient to use E-mail to send messages to people living in other countries. Instant Messaging is also a very good and well used communication service. It is very easy to have a proper conversation with someone for free and is very simple to work. The most common sources of IM is MSN or Yahoo. Another, common way of communicating is SMS, it is very easy to use, however, it is costly and it is sometimes hard to understand people's messages.

So therefore, I think E-mail is the best source of communication services although it is not always convenient to use a computer throughout the day and therefore SMS is a better option.
