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.…

Under the "Same" column, it looks like you need to add "Same price - $35". I stocked up on B+s over Christmas - oh well... The "at least 6x" performance claim should be "at least 3x" by the way, and even that is an estimate, not a guarantee. The 3x is on a single thread comparison, the 6x is on a somewhat synthetic multicore benchmark test.

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

For teachers one big issue is that you don't know if you can buy 100% compatible devices in a year's time in comparable conditions (price, bulk, availability etc). With Raspberry Pi you know you can.

I wouldn't be so sure about that - the article hints that they're trying to move away from the BCM2835, and in a few years' time the BCM2836 would probably suffer the same fate.

In any case I don't think I've seen anything from them about how long they'll continue making Pis, since they depend on Broadcom to provide the SoC.

On the other hand, AllWinner's answer about how long it will produce its SoCs... is surprising: https://olimex.wordpress.com/2014/11/27/how-long-olinuxino-w...

Except that Broadcom released "full documentation for the VideoCore IV graphics core, and a complete source release of the graphics stack under a 3-clause BSD license" [1], enough to enable a blob-free graphics driver. Code has already been committed to Mesa [2]. That is a lot more than you can say about the PowerVR core in the Beaglebone advocated by another response to this post. [1] http://www.raspberrypi.org/a-bi…

Of course you're referring to me. Arguing the whole openness of the video driver is a dead end [1]. If you want an open video driver use Intel, or AMD and be done with it. Give me a hand-cranked universal Turing machine and I've basically got the same device as a RPi. The only difference, it's cheap, and I don't have to get a workout hand-cranking it. Video is just a (semi-)fixed functional unit. Sure, it'd be nice t…

Do you think it is feasible to release a similarly priced, similarly capable device with completely open hardware?

The RPi has sold immensely to home users, but also in education. The foundation is also open to criticism and has shown in the past that they are willing to change their production when given the opportunity. They have moved most of their production to the UK for example, whereas the first boards were all manufactured off shore.

What about power consumption? I know it is the same power supply (5V, 1A), but this doesn't mean it uses the same amount of power...

The official power supply has 2A.

here's a comparison with the correct information - https://learn.adafruit.com/introducing-the-raspberry-pi-2-mo...

"... Best of all, the Pi 2 keeps the same shape, connectors and mounting holes as the Raspberry Pi B+ ..."

Phil, does this means the case (model A+) used in the 'Touch Pi' will be modified to fit the Pi2 at some stage?

Can you return them? If its less than 30 day...?

In the EU, the consumer rights directive allows you to return most goods bought online up to 14 days after delivery.

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

Nobody got fired for buying RPi?

Basically. When you buy RPi, you are getting access to a vast community of knowledge and guides, which is very useful for hardware projects.

Not particularly - there are several datacenters that offer raspberry pi servers as a commercial offering. I can't remember the name of the one near me (had a slick photo of black and green pi cases on their dc floor), but a little googling found this one: http://raspberrycolocation.com/

hosting pis without needing/being able to access gpio and such is a silly marketing fad. it must be so ineffective in term of space and heat that i would be surprised that they have a single beefy server running several pis in emulation for the clients.

A fad it may be, but I can attest to them having actual Raspberry Pi devices in colo or at least spending a lot of effort to make it seem like they've put mine in colo (more effort than would be required to just plug in the silly thing). I had a spare Pi sitting around so I loaded it up with a decent SD card, a USB stick, and a barebones Raspbian config and sent it off. It now functions as a backup MX, secondary DNS, a VPN endpoint, and a remote monitor of sorts.

It doesn't have to be powerful because I'm the only one using it. Since it costs me EUR0/month, why not? Isn't that what hobbyist tinkering is about?
