Believe it or not, it's been 12 years since Steve Jobs introduced the iPad to the world.

Since then, Apple's iconic tablet has gone through several iterations, adding cellular capability, sophisticated camera technology, and robust processing power. Initially confusing to critics who didn't understand the need for a device that was neither a smartphone nor a laptop, the iPad has proven the haters wrong and become a mainstay.

If you're in the market for an upgrade, the latest versions have come a long way since the original. The current iPad lineup consists of the iPad Pro, iPad Air, iPad, and iPad mini. Since, this year's Apple events announced the next generation of iPads (and iPad Air) which bumps the older versions of iPads one step closer towards obsolescence.
