I think Apple is a horrible, innovation-strangling company. However, being that way keeps them on top, and they have a clear influence on the PC market, as seen by the explosion of the tablet industry following the iPad, and the high number of All-In-One computers that followed widespread success of the iMac. If they aren't around in ten years, I'll be surprised, but twenty is a toss-up. I, for one, hope that Google and Microsoft can get all their awesome prototype tech together and conquer Apple, but for now, it's a very stable company with a huge fanbase. Even though I despise the company, they do put out excellent hardware, and the innards of their macbooks and other devices are incredibly clean and well-designed. Other companies, particularly Dell, are starting to follow this design model, which is the first step towards Apple death, but for now, they're staying put.
