Apple is quickly becoming one of America's most valuable companies. I sometimes think that Apple kills competition with its "walled garden" ideology, but any company which can afford to spend literally billions of dollars in R&D will give the consumer better hardware at a reduced cost.
Apple might be one of the healthiest companies around as well. I looked a bit deeper into their
financial reports and found the following:
Cash and cash equivalents ... 7,609
Short term marketable securities ... 17,187
It looks like Apple has 24.796 billion dollars in cash or liquid investments. Of course there are liabilities, but to have tens of billions just sitting around collecting interest isn't a bad thing.
