rasberry Pi (ARM chip computer)
bmarkus:
Well, it depends on your application. I do not expect to get a notebook or netbook performance of course. There are many possible embedded tasks where such a board may fit. For example for Amateur Radio APRS gateway to manage one radio and an Internet connection there are applications available written in C, Ruby or Python. My server written in Python runs fine on ASUS WL500 router with a 100MHz ARM and 32MByte RAM from USB stick on OPENWRT LINUX. OK, CPU laod is around 20% but who cares. Radio is connected via USB, no other hw is used.
A second hand ASUS router (first generation) is available for $49 including housing and PSU. Any hw which can do the same for better price and a bit higher performance appreciated. This is just one example, there can be many others. Well, you do need video output. What you need in connectivity:
- min 1x USB 2.0 (2x is better)
- 10 Mbit/s wired Ethernet
Optional:
- 1x serial RS232 port
- 1x WiFi
- sound interface
- floating point arithmetic for math intensive tasks
Can Raspberry Pi used for such application? I think yes. Is it competive for $25? Definitely.

hi bmarkus,
i agree with you that also minimum hardware offers wide fields of usage and even heavy usage.
the interesting thing of the raspberry pi is the hdmi and the grafic-capabilities
that are shown in various videos in the web... often poor grafic slows down tiny hardware.
the only thing i would prefer is a bit more ram.
i experience that almost everything what i want and need is possible also with older hardware,
but it's convenient to work in a 1gb-ram environment.
probably the few ram will be the only limit that will be a bit annoying.
but nevertheless it will be great experience to expand this little board.
i'm looking forward to and i hope that we will get tinycore on it!!!

Yes
The Rasberry Pi goes on public sale in about 4 weeks time..... or near End of Decemeber according to twitter.
All 10 thousand "parts kits" have already been ordered.
Assembly is by robot because the chip is special and needs re-flow soldering.
They are assembling them on a piece meal basis for say the first 500
computers......... and sending them out quikly....they hope people will bang away on the new boards
and report back that ALL is well in maybe 80 percent of reports.
When they have these 80 percent replies....they will then UPSPEED the manufacture and maybe
make 2000 computers and those will be on sale to the general public....and so on....3000 more computers
and so on.
WHen the webpage first starts selling they will perhaps ENFORCE a "buy one donate one" option
to try to stop a web site Frenzy....this will mean the computer costs 50 or 70 dollars for the first few
hundred items in weeks 1 to 5....after that, they will make the "buy one donate one" theory become OPTIONAL for the general public that are buying RP's. (So the computer will indeed by $25)
The computer will come delivered without any SD card. You must buy the SD card with OS as a seperate purchase from the website........or use your own SD card and download the OS from the RP website.
The computer will be powered by many CELL PHONE power bricks.....the RP has a micro USB power connector.
That's it.
There is no question as to "whether or not the Rasberry Pi" will arrive as is mentioned in this thread....it's just a case of when it will arrive within a 2 month elastic band period.
yes

Ahh
the final Printed Circuit board is finished for Rasberry pi.
(the exact size of a credit card)
http://www.raspberrypi.org/
That is an entire PC on a credit card. Just stop and think about that for a minute
or two.

Depends on how 'entire PC' is defined. For me it includes housing, power supply and connectors. A PCB is just a PCB.
In fact, technology wise nothing new in Raspberry. It is great especially its price, they have excellent PR and marketing, but it is just an SBC out of many.
A plug computer is much closer to 'entire PC' for example except HDMI video.
