In "Marketing Warfare," Reis and Trout explain that while you should take advantage of a competitor's weakness, you should never make it your primary point of attack. In stead, you should attack a competitor's strength. The problem with a weakness is that a competitor can fix it, nullifying your attack. In fact, they may already be working on a fix, so you may get to market and discover your entire strategy is bunk. Whereas they can't 'fix' one of their strengths. In more modern terms, attacking their strength is leveraging The Innovator's Dilemma. So about multi-tasking. Whoop-de-doo. This is a weakness Apple can fix with a minor point release of their OS. iPads have more battery and a faster processor, they are probably already toying with the idea. This is not a point of attack for Google. OTOH, the Apple Store is a strength for Apple. The well-behaved apps are a benefit for users, so having an open ecosystem is attacking Apple's strength. If Apple opens its ecosystem up, junkware, malware, and other forms of app garbage will quickly follow, which will eat away at Apple's control of the user experience. Thus, openness is a great strategy for Google to follow, while multi-tasking is simply something they should do but not hang their hat on.
