For starters, the reality is that Apple's revenue streams are quite diversified and their product portfolio is very strong. From iMac, to iTunes to iPods/iPhones/iPads.
So the notion that Apple would launch into litigation "just for the money" seems misguided, at the least - if only for the fact that if they lost the suit, there could be significant ramifications for their sales (e.g. an injunction against selling any of the products in the suit for X period of time, etc.). With sales and revenues growing as much as they are, a wrongly filed lawsuit can be even more risky than rewarding.
For a company as wealthy (and innovative) as Apple, there are more considerations than just protecting market share and trying to extract patent rent from competitors as a revenue stream.
There are many other companies that come out with many features in their products that Apple doesn't sue. See Windows, Safari vs Chrome, iPod vs Zune, Adobe Premiere vs Final Cut Pro, most "ultrabooks" vs Macbook Air, etc.
The issue here is that Samsung, HTC, et al. essentially have done what many companies in China have done. They acted like a hardware manufacturing partner - then using the inside knowledge they gained of the intimate architecture of the products, they reverse engineered them and competed directly.
That's like you hiring a web developer to build your startup - and both of you build it to traction, and once you take all the risk and prove the market, (s)he leaves and builds a direct competitor using his insider knowledge.
It's the most insiduous kind of 'IP stealing' that you can get.
If you had that done to you, and your ex-developer (in fact, he is still managing your codebase) is making a ton of money off of your ideas and IP in your market, I am sure you would be pissed too.
The money is just sprinkling on top.
Also, I think it is hard to argue that Apple doesn't pour their hearts into what they do. That's why they are the most valuable company on the planet and will continue to be for years to come. It's because of the rate at which they innovate.
Not the rate at which they copy.
So cut them some slack, and walk a mile in their shoes.
