Hello frinds
Screen:
The newer iPad mini comes with a Retina display. This offers a much higher resolution than the original iPad mini and it really tells. The screen is much sharper and brighter - its one of the best tablet screens around. Thats not to say that the original iPad minis screen is rubbish. In fact its decent. Video and pictures look good, its when reading text that youll wish for a higher resolution.
Processor:
The iPad mini comes with the iPad 2s A5 processor in tow. Its a little long in the tooth now but has no problem running apps. The newer iPad mini comes with the same processor as the iPhone 5S, the 64-bit A7. Youll find that 3D games, like Infinity Blade 3, offer more detail and 3D effects on the Retina screen of the new iPad mini. If you want to use heavy duty apps like 3D rendering and video/photo editing you may want to pick up the more expensive iPad mini, but if not the processor jump is less of an issue than the screen.
Camera:
The new iPad mini has a slightly better front and rear camera. Youll get better shots in lower light conditions with it.
Battery life:
Both iPad minis last about the same amount of time - 10 hours of constant use.
Nice an smart ipad
