We all have our favourites don't we? the little bits of software, the favourite can't do without application.
A post I read last night asked the question what would you load on a new office PC with Windows 7? The responses included a list of several really good applications including simple things like anti virus, codecs, opensource office software.
The list is of course potentially endless.
Being the cost conscious MTN Business person that I am I felt the list needed to have something that looked at ongoing rather than capital savings. So my suggestion was as follows:

If it is for office or even personal use I would want to have a simple messaging and even VOIP tool. I use SKYPE at home and in the office. Simple to use and gets communication round faster than email does. If you are going to be making calls to other offices then it can save you a lot of money on telecommunication costs. For overseas communications I use it a lot to suppliers in Europe.
