Please skip ARMv7 and jump straight to ARMv8 for Raspberry Pi 2. No need to force OS/app developers to support 3 different ISA's for years to come. Ideally it would also be dual core and have a clock speed of at least 1.2 Ghz, since that's what most operating systems need these days to run reasonably well, but I guess that depends on your target price. 1 GB of (LP)DDR3(L) RAM should also be the minimum for the next o…

That would make the http://www.broadcom.com/products/Applications-and-Multimedia... the obvious choice.

That's ARMv7.

Yeah, which is a shame because I think an Allwinner SoC or similar would also fix the other problems people are complaining about in the discussion, like the slow/unreliable USB and Ethernet and the lack of line-in. (Allwinner SoCs have proper USB and Ethernet controllers and audio DAC/ADCs onboard.)

Some of the Android "HDMI stick" devices I've seen running Allwinner SoCs aren't very fast either. Granted they're faster, but compared to SoCs in cell phones, they're dog slow. The Android builds also always seem to not work in one way or other.

Compared to SoCs in $50 cell phones? Remember to keep things in perspective. ;)

Curious they're explicitly naming this the "final evolution". First up, I'd be surprised if they continued with a "Raspberry Pi 2" soon. The RPi is still very adequate for its original goals in education and will likely remain so; it hasn't ever been quite enough for people wanting a cheap server or media center except for those with very modest needs. Given their announced goals, I doubt that the creators are going…

I think that the fuller quote "the final evolution of the original Raspberry Pi" is important. The word "original" in there doesn't lead me to believe they are at the end of the road overall, just end of the road for this one design. To clarify, I expect to see a more complete redesign in the not-too-distant future. If nothing else, you want to use components that are recent so you can keep producing more of them wit…

> end of the road for this one design.

Yeah, that's exactly the question I got from reading it. If they are implying the end of the road for this design, does that imply they have a next design? If so, why would they want to redesign?

> you want to use components that are recent so you can keep producing more of them without increased costs for legacy components.

Good point, didn't think of that. Is this a problem even on their scale?

Out of curiosity have they gotten netflix to work on the Pi yet?

I'd be surprised if they did. Netflix doesn't have a Linux client, and the only way to get it running on desktop Linux is using Wine with custom patches. Seeing as Wine depends on the CPU being x86, this method won't work.

I still can't see why would anyone buy one except as one of those toys that you buy and then gets tossed in the closet. 10 years ago I could see the appeal, but now? The robotics, home automation, and weekend project use cases seem like would be better served by a $5 microcontroller. Some projects, such as the weather station, justify the use of a full-fledged OS, but with the cost of buying an existing, proven, weat…

I'm currently putting together a data recorder for an academic experiment. It requires: GPS, Camera, Environmental data, inclinometer, and a few other odd bits. I could build up a custom system, but that is a big NRE expense for something that less than ten of will probably ever be produced. I could also use a "better" but less common developer board, but that path has its own problems. The experimenter could have stuck with a COTS solution, but the reason that I'm working on it now is the inconvenience and poor quality of the current implementation (lots of COTS stuff bodged together). Currently, they are using a lot of COTS stuff, and then putting the data together in batches. Even though it is a somewhat automated process, it remains slow, labor-intensive, tedious, fragile, etc. When I am done, I get to hand off an integrated, fully automated system that is flexible, built with easily replaceable parts, and best of all; due to the abundance of freely shared examples and documents, a grad student, or even an ambitious undergrad can take over and manage or even customize the system. Also, the rPi based system is much cheaper than the current system.

So, there is one pretty good use for an rPi.

For people saying they want a faster revision - do remember there are other computers in this form factor. I recently got an Odroid U3 and am very happy with it. Of course, it's $65, not $35. I tried setting up owncloud, nginx, a web server, etc. on a Pi and it couldn't handle it (everything ran, but terribly), the Odroid does well. I still like the Pi, though. There are some people for whom saving $30 really does ma…

Happen to know of any that accept the rPi camera, or an equivalent camera?

I'm still missing a normal round power plug, as the ramshackly micro USB draws much more power then the allowed 500mA. Also Ethernet is still connected via USB, and horrible slow.

The Ethernet chip is a new one tho - maybe it's a little less terrible? (No idea - my applications for the rpi don't depend on it being a speed demon on the network.)

Any recommendations for similar small/cheap devices with better Ethernet?

I made a home heating controller with temp plotting and frost alarm out of a couple of Pis. I don't think a $5 microcontroller would have run a tiny web server, tiny email server, or the plotter code that forms the core of the project. The Pi is a fine budget Linux computer. It's not fast, it's not powerful, it's not expensive. But it's fast enough and powerful enough for embedded applications you can put online with…

That sounds cool. Do you have any more details of the home heating project? I'm considering doing something similar.
