nice update, but shame they didn't go to ARM v8 since they decided to jump uarch from v6 anyway with this update.

Thanks, that's exactly what I needed to know. That's not too bad.

I was also quite surprised with the figures, but then I remembered that I made my calculations according to this post and its "worst case scenario" which predicted about 5W and therefore ~ 44kWh.

Electricity in CZ costs around 4.8CZK/kWh which is around €0.17/$0.2/£0.13 per kWH.

If it is just 2.4W or even 1.6W, it is still far less expensive.

You have to take into account the convversion loss in your PSU so even if the device consumes 2.4w total probably comes up to 4...5 watts or so.

so the most important feature of Raspberry Pi 2 is the increased power consumption from 1.6W to 2.4W ... the fact that it provides double the RAM and a faster multiple core CPU is nothing!

Then hear this:
Don't buy the Pi 2, because the Pi 3 is going to be released "soon"!

No, the real question is:
If you think you have a use for the Pi 2, why haven't you bought some other arm board yet?
The Pi 2 specs look a lot like a Cubieboard 2 or a Cubietruck. Granted, these are more expensive, but the Pi 2 is also quite late on the market.
So unless you have serious funding problems the niche the Pi 2 could fill should already be filled.

Right! The point is to bring your fuel oil bill down. The CPU cycles are just a side effect.
It's basically the Heatball principle:

That depends. Sure, if you have a burning need to do a certain task and are looking for a product to do the task, then you are absolutely spot on.

On the other hand, here is a cheap toy. And - yey! - it can actually do stuff! Why don't I buy one and play with it? There. A niche filled

I love it. 95% efficiency. But I would say that's way too wasteful. A good heatball should give at least 98%.

BTW, this sentence took me three reads until I got it. What a difference a missing comma makes: "The input energy that a heatball consumes is the effort, its heat is the benefit while light portion is the loss." (Missing comma after benefit.)

The Pi has, however, some advantages over the Cubies and most other ARM boards:
  • MUCH better community support (I've got a Cubietruck, the hardware is much more complete/promising - but try to get a recent kernel for it...or drivers for the CedarX multimedia unit...)
  • Most parts of the hardware are well documented now (Broadcom has openened up quite a bit...)
  • Camera interface, infrared camera available (and RAW support)
  • Free Mathematica package (probably more useful now with the quadcore and 1Gb RAM)
  • Lots of extensions available

Especially because of it's community, it's still the most fun ARM board for meat the moment, despite its disadvantages:
  • no WiFi/Bluetooth on board
  • no SATA
  • no real-time-clock
  • no battery interface
  • GPU a bit dated

BTW, I love that sentence:

During its use as a heater, HEATBALLS have an unavoidable emission of light in the visible spectrum. This light is harmless and cannot be used as a reason for reclamation.

Was considering buying a Model A... dunno what for - fun, maybe? - but with 2's specs, no way I'm doing this. Still, the major problem is - what the hell to use it for? =\
