Those two statements have little to do with each other. The current (and upcoming) version of iOS still works largely the same way as iPhone OS did 6 years a go.

Modern mobile OSes are easier to learn than desktop OSes and are less encumbered by malware. For someone who has never used a desktop computer or the Internet, starting off with a good tablet instead of a personal computer is a better choice.

> while not coparable to XP

Still, in the tech world, half a decade is pretty close to eternity anyway. XP sure had a long life.

As I understand it, XP wasn't meant to do that either; the fact that it lasted so long was more of a series of mistakes on Microsoft's part in getting a replacement out the door. I'm happy to be corrected, though.

Even if Vista wasn't delayed, XP would have received security update support for at least 10 years after release.

Microsoft has insanely long support cycles for their products. Windows 8 will be supported until January 10, 2023. http://windows.microsoft.com/en-US/windows/products/lifecycl...

Elderly people suffer from planned obsolescence, too.
