It seems right now that Apple just can do no wrong. With record sales of its devices and huge amounts of money sat in the bank, it's all very rosy over in Cupertino. But other companies have had successful periods before, only for things to go a little awry in future years.
Despite great results from Apple ever since Steve Jobs returned to the company back in 1997, it wasn't really until the iPhone's introduction in 2007 that the world really took notice of what was going in at 1 Infinite Loop.
Now it's a worldwide phenomenon, with people owning iPhones who would never have contemplated picking up a Mac.
Throw in the beginnings of a tablet market that is still being dominated by the iPad, and Apple have every right to feel smug. But it may not last forever...
