It's not just the hardware peripherals, tutorials, books and community count for a lot also.

Agreed. Among all the SBC forums, the Pi's is the friendliest community I've come across. You're almost guaranteed to get a reply and it's usually a useful one.

Try asking for something as simple as electrical specifications on the GPIO pins (Broadcom released the GPIO registers, but oddly enough not the electrical specs):

ARMv6 still? I don't see how that's necessary to save on the BOM. I hope legacy code was not the deciding factor here.

According to [1], these will be ARMv7 architecture Cortex-A7 cores. Looks like we'll know for sure only when the foundation announces a public release. [1]: http://www.cnx-software.com/2015/02/02/raspberry-pi-2-model-...

Linked article on the Register has been updated to confirm ARMv7/NEON http://pastebin.com/raw.php?i=v0LVywBi

Finally more power for graphics. I am seeing some interesting VR projects with the more horsepower, especially since VR is THE thing right now. And the pi is light enough for head-mounting!

I'd love to see this happen. But i think that's very wishful thinking, outside of some very simple scenes - my R9 270 struggles to maintain framerate with some DK2 demos and the pi's VC4 isn't remotely in the same league.

I think we will need to look at streaming scenes from a more powerful machine rather than creating them on board. I don't believe we are ready in any way to process that much information on such a small system at this time (HoloLens also gives out quite a lot of heat from its on board processor). The old pi had trouble streaming higher bitrates, though then we still have the same ethernet so I am not sure how much is possible.

Ok. I find it rather rude to call a company 'assholes' for doing something that is 100% within their rights. They're releasing a chip that powers a relatively cheap fairly powerful computer, have supported the effort in as many ways as they could without giving up their competitive edge (when you're in a leadship position it is sometimes quite risky to open up too far), nobody forces anybody to buy the product and la…

I think aswanson is simply expressing his feelings. Broadcom has garnered goodwill from being involved with the Raspberry Pi foundation. Goodwill, I must add, from a broad swath of people who are not too technically inclined. Yes, the computer (or device if you're lacking generosity) is a god-send for those without the capacity to buy an Intel/AMD-based PC, but let's not kid ourselves: the device is less open than a…

The Odroid C1 uses an SoC from Amlogic, which is also American.

Awesome!! I just wish they would release one with onboard Wifi instead of ethernet. I have no statistics to back this up, but I'm pretty sure that USB Wifi adapters would be the most common accessory.

I use the onboard ethernet pretty constantly, mainly because I find the wireless to be finicky and hard to troubleshoot when you're running a headless setup. I can always plug in an ethernet cable, though...

Agree. However Finally I was able to keep an uptime greater than 2 months on my Pi by using a wifi dongle and a bunch of cron scripts to keep alive the connection when my router reboots or the dongle 'freezes' which seems is a common issue when using RPi of any kind :(

How does this compare with the ODROID-C1? http://www.hardkernel.com/main/products/prdt_info.php?g_code...

The ODROID-C1 looks very nice. My main hesitations would be available drivers and community size. They may have drivers for everything, I don't know. It is nice to see that a somewhat recent kernel is available though (3.10).

I recently ported several projects I had from beaglebone black to an Olinuxino A10 Lime. A lot of stuff was relatively painless, but I was never able to get Node.js to install. I also got bit in the ass because I laid out and ordered PCBs assuming all of the SPI channels had drivers, when only one was there (of course, not the one I chose).

Embedded Linux constantly reminds you that you are standing on the shoulders of giants, and you can go from feeling like a wizard to feeling like an idiot real quick when some part of the system isn't working. That's where having the communities like beaglebone's and raspberry pi's really pay off.

Depending on what you're trying to build, a Spark Photon might be a better fit for your project.

Why would anyone buy this over the much more powerful ARMv7 odroid-C1 for $35 that has been out for months now?

"... Why would anyone buy this over the much more powerful ARMv7 odroid-C1 ..."

It's not just the hardware you buy into. You also by default have the available operating systems, the software available for the OS and the community.

What's the same: - Same form factor as the model B+ (your enclosures and daughter boards should still fit). - Same full size HDMI port - Same 10/100 Ethernet port - Same CSI camera port and DSI display ports - Same micro USB power supply connection What has changed: - A new turbocharged Broadcom BCM2836 900MHz quad-core system-on-chip with performance at least 6x that of the B+. - 1GB of RAM Source: http://raspberry.…

Driver support in the Odroid C1 downloadable Ubuntu image is complete (as far as I can tell) and Ubuntu runs quite well.

I was unable to get X running on Arch Linux despite the drivers being available.
