Apple

[Grieve]

Most of these firms, especially Apple, have almost all their cash overseas, so there is very little they CAN do with it, without losing tens of billions to taxes. Although it does seem a tax holiday may be getting more likely.

Saying they are not doing anything innovative is a little blinkered. Most companies don't broadcast every little thing they are working on like Google and, to a lesser extent, Amazon do. The Internet of Things is going to bring about massive change to the world in the next decade or two, and I guarantee all these companies have secret projects in areas we haven't even imagined yet.

But sure, until then Apple will focus on iPhone, and Microsoft on Windows, and Google on search/ads, and Amazon on selling stuff - it's their bread and butter.
