Then again, as a customer, the $35 + SD card price of Raspberry Pi is pretty appealing.

The price of the Pi is a bit like stone soup. Sounds cheap but not when you add it up.

You have to add keyboard, mouse, SD card, power supply and an HD TV, before you get a working system and then it is Linux which totally cripples it from the point of view of real time control.

Add to that a USB port that doesn't work quite how it should (you can't get a USB camera working) and it is not so much of a bargain.

It has however just been upgraded to 512MB of RAM, as it can only run code out of RAM, this is the same as the Due (well a bit less because Linux has to run there as well)

The BeagleBone is quite nice. More expensive than the RasPi but much more capable, and it could be argued that it's better value than the Due. I've got one, with a prototyping cape (Bone capes are like Arduino shields). There are lots of capes available now.

It depends entirely what you want to do with it.
Basically the BeagleBone is a Linux box with all the baggage that involves - no real time operation your thread can be stopped at any time. Therefore no multiplexing, software PWM, no uninterrupted A/D and D/A conversion for simple sound recording / generation, no exact timing of pulses, no driving stepping motors or servos.
