Why won't we see Mxit in the Developed Countries? Interestingly this is one of those technologies that has an easy fit to Africa even though it may never gain traction in developed countries.
Mxit is offering a simple Instant Messaging service which has found a ready market in South Africa. Such an offering would not really save contract based users money on their SMS, and is almost too simple a service for the sophisticated user. Hence its market penetration in developed countries is likely to be limited.
