And Android has like 80 percent market share outside of US. So maybe it's time for developers here and elsewhere to forget about the "Macs/iPhones 'everywhere', therefore let's build for them first" Silicon Valley culture, and start developing for Android first?
With J2ME phones rapidly declining as they are being replaced by smartphones (even $50 Android smartphones going into this year), and the vast majority of those smartphones being Android (even Microsoft is considering replacing Nokia Asha's OS with Android, therefore killing another a huge chunk of the J2ME market), Android's platform is basically the "new J2ME". So to follow the author's own advice, you should build an Android app.
The choice of platform should be made based on the value proposition. In the case of whatsapp, the business is based on undercutting the price-gouging of SMS with a superior alternative for $1 per year. This makes it affordable and appealing to everyone, including (especially) J2ME and Android users in the developing word.
If your app fits this profile, definitely go Android first.
But.. if your app is more appealing to people with discretionary income, you are shooting yourself in the foot if you don't start with iOS because that's where the users with money are.
