A timely reality check
Apple is in a terrible position here because the future of mobile apps are Web apps, and Google excels at making those. Apple needs Google, it's most dangerous competitor in the mobile Web market, to keep building apps for the iPhone. Google would be foolish not to since the iPhone still has the largest reach of any modern Web phone. But it will no longer be a priority.
The sad thing is that Apple has been here before?with Microsoft. In the late 1990s, Apple had to beg Microsoft to keep building Office for Macs. Now it may be in the same position with Google. There may be more than 85,000 apps in the App Store, but it is only a handful which actually drive purchases. If Google Maps Navigation becomes one of those types of killer apps, Apple might need to do some begging first before Google goes through effort to make it for the iPhone.
