Senator John McCain questioned Apple CEO Tim Cook about the company's tax practices during a hearing on Tuesday, but ended the hearing with the question: 'Why the hell do I have to keep updating iPhone apps?'

"What I really want to ask is why the hell I have to keep updating the apps on my iPhone all the time, and why you don't fix that?" McCain asked Cook.

"Sir, we're trying to make them better all the time," was Cook's response.

Cook spent the rest of the hearing defending Apple's offshore decisions that result in low taxes before a Senate subcommittee, saying that Apple uses no "tax gimmicks."

In addition, during the reading of a prepared statement t the hearing, Cook revealed that Texas will be the location of a new factory where Apple will assemble Macs.
