It looks like the Rascal Micro machines are targeted to act as Python capable drop in networking and compute upgrades for 3.3volt Arduinos. At least for lower current I/O. If I read the datasheet right, the I/O pins max out at 8ma.
A stock Arduino runs at 20Mhz, these can run at up to 400Mhz (not counting overclocking). These have well integrated USB and ethernet. In addition to the all important Python environment, you get all of the other Unix/Linux history. Programs can use Email, webget, and many many other ways to communicate with the outside world, right out of the box. Crontab and at are the classic scheduling apps from the 1970s. These can be augmented with much more elaborate schedules, if desired.
The Raspberry Pi developers mortgaged their homes, so the first batch of Raspberry Pis model B's could be sold at the target price of $35. I expect the price of Rascals to drop down if they do well, but I don't expect the developers to risk their homes.

There's certainly going to be a lot of competition on price around these kinds of boards, partly due to the Raspberry Pi getting a lot of exposure, and partly because the market was moving in that direction already. Previously, I thought that the Rhombus Tech initiative was the thing to watch, but the mailing list seems to have deteriorated into a combination of infighting, apparently hare-brained schemes involving hardware patents, and a continuous shopping spree for cheap gadgetry. That said, it did peripherally make me aware of these Olimex boards that seem pertinent to this discussion.
I think a lot of people believe Arduino's days to be numbered in the face of more sophisticated boards becoming available at the same price point, but the simplest of Arduino solutions are arguably closer to the kind of system that the Raspberry Pi people seem to want to recreate: programming on the bare metal, the simplest of operating systems (in fact, you roll your own), direct access to hardware, and so on. The very limited RAM of the Duemilanove might be too restrictive for a general purpose computing environment, but it wouldn't need much expanding to remedy this.

The Olimex boards look interesting. The Olimex website makes it difficult to link to individual products or product families. So apologies in advance if I get the links wrong.
The board that is of most interest today is the iMX233-OLinuXino-Maxi, because they have it up for sale on their ebay site. It is part of the OLinuXino family (text) also see OLinuXino links. The other members of the family aren't ready yet.
Olimex has dozens of other products that are available through distributors around the world, so I assume their Linux products will be available through their usual channels once production ramps up.
The classic AVR based Arduino still wins on availability. It will probably win on current drive, and power consumption, for years to come.
