Visualising MIDP Performance Change

Previously, I posted a density plot that demonstrates how MIDlet market share changes as a function of handset heap memory and performance (as measured by the JBenchmark 2 score).

In this post I provide a visualisation showing how market share has changed over time.

The video, below, shows how performance is improving over time.

The video shows how application market share is affected by heap and performance. Each frame is based on one year's worth of data, up to, and including the month shown. For this reason, there is a large amount of noise in the early frames as there were very few MIDP 2 handsets in 2004.

To obtain a very large market share (90+%) of handsets released in 2007, you have to target pretty much the same performance criteria as you did in 2004. In the mid range, handset performance can be seen to be steadily improving.

What Next?
Next, I will run the numbers for Nokia, Motorola, Samsung and Sony Ericsson handsets.
