Improves on the already excellent iPad 2 in the most logical areas by changing one of its few weaknesses (low resolution screen) into one of its biggest strengths (very high resolution screen). Because of this, they made the tradeoff of having slightly heavier device, but considering most people spend a lot more time staring at the screen than curling it, it was the right one.

LTE is another welcome upgrade if you have coverage (I get about 10 megabit at home with 2 bars, a higher strength area might yield better results).

The rear camera went from grainy uselessness to actually respectable pictures - I will still be using my smartphone for photography, but it's nice that the iPad now has a decent "eye" on the back. Should be great for photographing whiteboards, etc in the office.

With Apple continuing to improve its very competent suite of touch apps and continued developer support, the iPad remains the product to beat in the market.
