Typing this on my Raspberry Pi. Using a class 10 SD card, it is quick to boot, but trying to run a decent non hardware accelerate 1080P GUI is too much for it, it is like wading through treacle. Managed to remote desktop to Windows 7 laptop and it is still deathly slow.
The attraction is perhaps the GPIO pins and as an upgrade to a microcontroller board it is amazing, but in no way is it sensible for web browsing, thin client or response enough for an educational tool to teach visual based programming.
Now I have to scroll down to hit the reply button. It will lag horribly! CPUusage is hitting 100% as I type in this window and whilst it doesn't miss keystrokes it can easily be a few words behind my typing to actually display what I am typing.
Edit: above I'm missing the point, most microcontroller boards are way more expensive and way less powerful. Hopefully hardware accelerated GUI will be fine, we'll have to see. http://www.thesinglestep.org/thoughts/rspi/

Made a box for it from here: http://www.thingiverse.com/thing:25100
Laser took 2 mins 30 to cut and engrave all the ports. Assembly took longer and I had to redo some of the panels as they were designed for M3 bolts and I only had M4.
Excuse the iPhone pic in poor light plus cat hairs:
Will see what developments ensue, I can see it controlling my garage doors very nicely, when I build the garage next year.
It could also make a very nice ECU too.

I take it all back, Quake 3 at 1080P is awesome and smooth. Can't get the sound to work though!
The GPU is quite something, the CPU is crap. Seems the wrong way around!

The Debian squeeze is the one I've been using.
The whole bulk of an OS is interesting for devices like this that are a cross between a bare metal microcontroller and something that has a 1080P multimedia, DHCP IP address, USB host.
The R Pi seems compromised in that it sits uneasily in both camps - the CPU as presently programmed is too slow for the "computer" role, but the OS is too bulky and the GPIO pins are too limited for the "arduino replacement" role.

Marketing of the wife's new laser business is interesting. Work is increasing through her personal networking, visiting shops etc, enquiries coming through businesses for custom work through organic SEO, but since we haven't done any paid advertising and don't have distributors yet, the volumes are very low so far. She put a few products on Ebay and even though they were at cost they didn't sell, but did result in a few queries and sales for customised stuff.
Lots of people doing R Pi cases, but they seem to sell well, although what I showed is not our design.
I've been so busy with other stuff to know where she is on her marketing, but volume is my main anxiety/makes me impatient, previous work I've done has had an instant market as it steps into established roles or where demand was already present.

A friend of mine will be sending a Pi into space'ish to help send back live pictures, one takes 15 minutes currently, but double bandwidth for the flight. He's already an altitude record holder, with a good retrieve history, so a good bet it will be a success. Just waiting for the launch date. Good Pi right there.

I finally got around to installing Raspbmc and it works very well.
I think it is a great bit of kit to get children into programming if they can be bothered. ICT at school is a joke and doesn't even explain about networks or how computers work just uses out of date software like serif to create posters.

Just got an email that mine is on the way. Been years since I did some 'proper' coding using UNIX...
As an aside, they're just about to release a new image of Debian that is coded to better use the hardware FPU - see http://www.raspberrypi.org/archives/1565 for a video of it web browsing a t a decent speed (albeit on a Pi that's been overclocked).

How's everyone getting on with their RPi's now?
Mines running as a web server hosting a light-use phpBB forum and a Wordpress blog. It's running Debian "Wheezy", Lighttpd Web Server, PHP in FastCGI, MySQL Server & PureFTPd. Simple enough to move over from my WAMPServer install and runs superbly. I fancy a new 512kb version now to do some more playing

Typing this using RISC OS and it is quite fantastic. Responsive by modern PC standards using the desktop and internet. It doesn't have flash or javascript in the supplied browser so far. Even though I believe it is without GUI acceleration windows move with great fluidity. Best of all hit F12 and type "BASIC" and you are in a very fast BBC Basic and it apparently isn't too difficult to control the Raspberry Pi IO from there.

Its qoing to get a whole lot better very shortly 
Android has been ported
First two goes were slow, but the third is meant to be very smooth and stable,
There just fianalising the package before release,
No app store included, but apparantly you can install APK's
Mame, mupen and FPSE here we come
oh and it runs XBMC too

Bit of a bump I know, but I've only just heard about these little things. I know, behind the times.
Does anyone have the Model B, i.e.; the latest one, and if so, how's XBMC on it? How does it compare to, for example, an Apple TV1 running XBMC? I have an ATV3 sitting in my living room, and I'm hoping for a JB so I can run XBMC on it - that or Apple pulls thumb out of **** and decides to allow app development for it and then XBMC gets ported to it, pretty unlikely though. I also have a DLNA compatible blu ray player, so can stream some media to it, but I'm wondering if a Pi could be a better solution to both of those, possibly replace my ATV1 with one.
