is the NEW ipad 3 worth the upgrade from the old ipad 2
If money is no object, and you want a somewhat better iPad... Yes.
If you are expecting a huge upgrade, it's debatable.
A side by side comparison with my iPad 2, the display on the 3 is better, but I do think it was over-hyped.
It's a bit more comfortable due to the thickness, but the weight is a bit of an annoyance for long term use.
If it's your only device (you don't have an Apple Laptop) then perhaps it would be worth it, because you're using it for everything.
If you already have an MBP, or MBA, iMac or the like, then you can easily pass on the iPad 3.
Step back for a moment and remember this... it's all roses right now with the new iPad. When the newness wears off, you will hear about the issues that are to be expected. Nothing is perfect and neither is the iPad 3.
I bought one because I could, but do it again? No.
It's just an extra around the house browsing device for me.
