Nope.

The vast majority of libraries won't work with the new Due, and some older shields (like expansion cards you put on top) won't either.

The ATMega based boards are cheaper & are easier to get hold of.

Additionally, the Cortex I/O is 3.3V, not 5V tolerant which makes it easier to accidentally fry.

It's exciting stuff for experienced arduino users who like the ecosystem, but if you really want it I'd wait perhaps another hardware revision so the hardware & software stuff is properly in shape. I've been using arduino since the early days and, trust me, you don't want to be the first one hitting obscure preprocessor/compile bugs. You will also be amazed at the amount of performance you can get out of the little ATMegas when you don't have operating systems sucking up all your cycles!
