Focus on one app: Whatsapp. Say this is the mid 90's and you want to make a dent on the mobile market. So you keep costs low and put a cheapo camera on the thing along a semi-decent mp3 player. But there is one big problem: your Konia 1 phone does not run SMS. Nobody buys the thingy. What went wrong? Oh, its quality, let's put a hi-end camera and try again! It's all about the apps that people use. Remember MS Office? Oh, nice Macs said the IT managers, do they run MS Office? Go cut a deal with Zucker and get Whatsapp for FFOS then the phones will sell.
