Well, if you leave the TV out, then that adds another 50% to the price, roughly, if you assume you can get the keyboard, mouse, microUSB charger and SD card for $15-$20. Not too bad, I suppose.

A BeagleBone goes for $90. So, looking system to system, it's just over a 2:1 ratio: $110 vs. $50.

For many engineering geeks, I doubt the $60 differential is a huge deal breaker if you're only buying one. If you're on a much tighter budget, though, or buying many of these (either for many projects, or, say, outfitting for a lab full of students), I can definitely see the lower price being very attractive.

And to point out the obvious, I include the developing world under "much tighter budget." If the goal is to get computers into as many hands worldwide as possible, the BeagleBone is a much harder sell.

If you're just selling to tinkerers that have extra cash, it's hard to see how the Raspberry Pi is dramatically more compelling than the BeagleBone unless your project requires a many boards. I think distinguishing between different goals and scenarios might be helpful for evaluating their relative strengths.

well, does the beaglebone include the keyboard, mouse, charger, and an extra SD card? or would you have to get those for it as well?

Also, many people will have stray keyboards and mice around.

In the system to system price, I included the same $15 - $20 adder. Actually, I computed a $20 adder for the BB system vs. $15 for the RPi. If I correct the math, it's pretty much exactly 2 to 1: $90 => $110 vs. $35 => $55.

And sure, you may have a spare keyboard or USB power adaptor around (many tinkerers will), and that makes a difference when you're buying one or two to tinker with. My point is that you can't really count on that if you're, say, outfitting a classroom or doing some other mass deployment.

That brings me back to the final point I was trying to make: Tease apart the different scenarios where you might be choosing between these, and see how the strengths and weaknesses of each play into those scenarios. Reading through these threads, I see a bunch of goalpost shifting, because different commentators are assuming different use scenarios.
