Your initial statement was a bit more important than you may have thought. At a 0% profit rate, ANY business would have to do something or face being driven out of business. And at a 100% tax rate, well, it would be close to impossible to run a modern business, so the point is moot.
You argue that any tax increase on profits will be sent directly to the consumer. This, however, carries a number of implicit assumptions:
1) Increasing the price will not impact sales: Increasing the price by x% may make fewer consumers buy the product, decreasing the sales by y%. This could easily lead to lower total profits for the corporation.
2) No competition: Competing companies may opt not to increase prices and be able to undercut prices. This allows them to build a larger market share by attracting the customers of those corporations that increased prices.
Regarding your arguments on cutting cost, this will happen regardless of taxation. Any corporation in a Capitalist economy will look for ways to minimize costs in order to become more competitive and drive out competition.
I never understood why people think it's a good idea to enter (or even worse, store) credit card info in a phone. That's the height of stupidity, in my opinion.
It's no less secure than your PC. Actually, the average Joe's automatically-updated iPhone is probably more likely to be free of malware than his Windows PC.
It is also a lot easier to steal Joe's iPhone than it is to break into his apartment and run away with his desktop PC
