After reading the first 15 pages or so I must say that for most of the projects offered, a R-Pi makes not that much of a sense.
For any kind of "clustering project" I think that the R-Pi is totally under powered. A regular (new) PC will be much faster than maybe 10 R-Pi's connected together. Maybe also it will be cheaper than those R-Pi's.
For any kind of "Hardware control via Network" type of project the R-Pi seems endlessly over powered. Like for controlling your "coffee machine" is absolutely nonsense to use a R-Pi. Use a Beckchip intead, they have ethernet on board and meanwhile only cost around 5 Euros and have a 186 CPU with DOS on them. For having one command every 10 minutes this is definitvely enough.
Where are the really good Gaming and Multimedia Projects ?
(NAS is also boring, most routers nowadays already have a USB port for NAS purposes. And you cannot skip using a router, since almost allways the modem is buildt into it.)
I am thinking of the R-Pi rather as a regular "general purpose" PC. I will use it as exactly that: a PC for anything.
Well, while I might argue that the point of clustering is like any task performed by two or more people working together is that the performance gained is not a linear progression (i.e. if I can do one unit of work, the performance gained is not x*1, where x = the number of people working on the task), I do also agree that clustering with an ARM system probably wouldn't be the best use as you'd still need a master PC to manage the cluster.
There's actually quite a few multimedia project ideas stretching from the basic media center PC, to a bare bone distro designed just to load various emulators. Some people have even talked about trying to get an emulator for sharing home made games (kinda like RPG maker?)
As for everything else, well I certain agree that it's a little overkill compared to an atmega chip or pix, it does have a distinct advantage in that it's a true, full OS and therefore allows for a more varied programming environment and with a $25 price tag, it's price is on par with the arduino.
