There are millions or according to some more than billion phones that support JME and that number is growing every day and will grow in many years to come�
iPhone is cool because it is iPhone and has good marketing but it is an average phone with only 2 mpx camera, no MMS, no Java support, no Flash Lite support� to capture vide one has to buy software� and in many countries it is not cheap so I don�t think that it will be sold in 400 or 500 million examples like Nokia phones or 100 million like Sony Ericsson and yes they support JME. Plus Motorola, Samsung� Maybe 10 or 20 millions a year.
Android is cool and if it becomes popular I don�t think that Android phones will �kill� other phones that support JME. Many JME phones are cool and good and probably will be cheaper than many Android phones�
