Definately want one, but I'll wait til the frenzy dies down a bit.

Looks to have been a mistake.

Thanks TheBilgeRat!  Ok, I'm back on for April again.

Well, once you get hold of your Pi you may be after one of these:

A nice case IMHO.

I just took a look at the Shapeways site too. Looks like a few cases are available.

The Raspberry Pi is a very interesting product, but I have one question about it.

If it only comes with 256mb of combined RAM for both the GPU and CPU to share, how is it not going to run into low memory problems when running Linux?

Is the version of Linux that is designed to run on the Raspberry Pi some special version that is extremely tiny in size and memory usage?

For comparison, my Efika 5200b came with only 128mb of motherboard RAM and has a 128mb VRAM Radeon 9250 video card and runs a very tiny and efficient MorphOS2.7, but under certain conditions can run low on RAM.  In fact many people would not buy it due to it's limited RAM capabilities.

Isn't the Raspberry Pi going to have the same kinds of problems?

Just a question that I thought deserved being asked.
How are you helping the Amiga community? :)

Very good question. They've got a custom Fedora spin for it which I'd bet they've been tweaking, I haven't looked at it though. Honestly I'm much more interested in running Haiku or RISC OS or something on it than another Linux distro...

I'm holding out for the $25 model, so I'm already prepared to wait until year's end.
I'm not sure just what I'll do with it once I have it.
Space probe?  Mini arcade cab?  Love tester?  Who knows?!

That's pretty much my thinking too. At the price of a single video game it's worth getting just to have a play with it.

Also, this:

Especially to the "Its an underpowered, worthless POS!!!" crowd.

Also, there is no issue running linux in 256 MB.  There is a problem, say, running LibreOffice, a 720P video in Mplayer, TuxRacer,ripping a CD, and playing on armor games in 256MB of memory at once, maybe...

@TheBilgeRat
"twice as powerful as iPhone 4S GPU"

I think no one has said it has weak GPU power?
It's GPU outperforms cell phones.
It will run tiny games and other small apps well.

It is weak for desktop kind of use.
No L2 for CPU use, shared RAM, no decent mass storage interface, ...

GPU: "roughly equivalent to Xbox 1 level of performance"
CPU: "Overall real world performance is something like a 300MHz Pentium 2"
http://www.raspberrypi.org/faqs

For porting hobby OS:
"To get the full SoC documentation you would need to sign an NDA with Broadcom, who make the chip and sell it to us. But you would also need to provide a business model and estimate of how many chips you are going to sell."

But as it anyway would be pretty steep downgrade from SAM440 kind of HW, AOS4 kind of OS + SW would never be an option for it.

...and suddenly it isn't $35 anymore, and with 8GB storage, power supply and cables on top, it's crawling up in Efika MX price range (but not in performance, features and usability). Many a little makes a mickle... ;)

I guess you can customize/strip Linux to "run" it on very slimmed down environments, it's only a matter of lowering your standards according to what's realistic given the conditions. Problems *will* arise however, if you want something close to what could be called a full, usable desktop environment, there is no magic way of circumventing missing HW resources. A special, custom build will probably be required anyway, since most major desktop distros doesn't support ARMv6 anymore (according to the Raspberry PI wikipedia page).

Seeing that the Raspberry PI lacks real storage (no real SSD on board), I guess any memory swapping (and all other "disk" operations) will have to use a slow (in comparison) SD-card...?

Or you could wait for my case for the raspi and support an Amigan ;)

Then the storage alone will probably have surpassed the entire Efika MX system in price...

Lol... No more than putting the same thing on an  ;) moot point anyway, as I want to run AROS on my Raspberry Pi.
