Dealextreme sells the [URL="http://www.dealextreme.com/p/hdmi-to-vga-video-converter-71816"]$32 HDMI to VGA adapter[/URL], if you would prefer to deal with them rather than eBay.
If you're interested in a tablet and don't feel like hacking something together, half-decent tablets exist for about $100, for example: [url]http://www.dealextreme.com/p/tm7022-android-4-0-tablet-mid-w-7-capacitive-wi-fi-tf-slot-and-mini-usb-black-1ghz-8gb-115316[/url]
Of course, just buying one isn't any fun. Though it's a bit more portable and works out of the box.
I want one of these for a media center, but I'll probably wait for the version with the case.

I’ve got some bad and good news about manufacturing. The bad news is that it’s taking a little longer than we’d hoped, because the factory had some trouble sourcing a specific component. The quartz crystal package we had chosen when we thought we were manufacturing in the UK is readily available over here in Europe, and was the cheapest we could find; but it turns out that in China, that crystal package has been overtaken in price and size by a smaller, cheaper one, so the one we’d designed for has been a bit hard to find. The factory has sourced crystals now, so we’re all go. The good news is that this finally means we have a date for the first batch:[B] the boards will be finished on February 20[/B]. Eben and I may be going to China to make sure that the boards can be brought up properly for that date if necessary. We’ll be airfreighting them to the UK immediately, so you should be able to buy them before the end of the month.
There’s another big piece of news today. We’ve been leaning (gently and charmingly) on [B]Broadcom, who make BCM2835, the SoC at the heart of the Raspberry Pi, to produce an abbreviated datasheet describing the ARM peripherals in the chip[/B]. If you’re a casual user, this won’t be of much interest to you, but if you’re wanting to port your own operating system or just want to understand our Linux kernel sources, this is the document for you.

We really appreciate it.

This looks almost like the perfect solution for a portable little media center.
The datasheet for the CPU is now available:

This is a REALLY awesome case.
I tought of this idea:
Get
-A cheap pocket projector
-Battery pack
-Raspberry
-Small rollable keyboard and wireless miniature mouse
-Some wires
-Something for casing
It wouldn't be too cheap but imagine: a portable projector computer. That would really be useful with the 1080p video and all.

I actually have one. So it's probably gonna be one of the first things I do with the Pi.
Also, I want to see if I can fit the Pi + projector + accessories in a metal lunchbox.
For people who think the Raspberry Pi can replace an Arduino, there's [URL="http://uk.mouser.com/ProductDetail/STMicroelectronics/STM32VLDISCOVERY/?qs=Sq9754QpLBjqJpXVpJuUgA%3d%3d"]this[/URL] and [URL="http://uk.mouser.com/ProductDetail/STMicroelectronics/STM32F4DISCOVERY/?qs=J2qbEwLrpCGdWLY96ibNeQ%3d%3d"]that[/URL] which will be more suited for what you are looking for. The Raspberry Pi is a computer, not a microcontroller and I think it will be pretty hard to access things like SPI or I²C and get the timing right

I think the plan was to use GPIO for those types of things. The Gertboard video gave me the impression that the code wouldn't be too difficult, though probably more so than the Arduino.
Another idea I had was some sort of roll-your-own home automation controller. You could have a few temperature sensors, cheap IP cams, some relays or X10 modules attached to the GPIO pins or through the network. A smaller LCD screen (15" should be enough) could display the cameras, sensor data and the states of the controllable appliances. Computers could also be controlled using Wake-on-LAN. Perhaps it could be controlled using a small remote or a USB numpad. Ideally, it would be accessible through a web browser.
I bought some 1wire sensors a few months ago in hope of building something to give me the outside and inside temperatures, though I've shelved it since I felt too tired after school to continue learning python.
My plan was to connect the sensors to a Teensy microcontroller (Small, cheap, Arduino compatible), have the Teensy read the sensors every minute or so, then output the readings to my Ubuntu server running a python program that reads the incoming serial data and generates a small image in /var/www (The directory shared by the web server) that could be embedded into a website and/or viewed from my Nexus S.
So they should be out soon being that manufacturing should have finished three days ago.
I hope these don't sell out in the first 3 days. I really want a model B.

Three days is being a bit generous, I'd expect them to go sell out in a few hours.

instead of buying touchscreens, can't you use this?

Maybe a really thick GB Advance.
Or the good ol' gameboy brick:

[QUOTE=Baldr 2.0;34837703]From the things I see the GBC would be a really tight fit.[/QUOTE]
If you want to keep the gameboy advance style you could mod a gameboy advance carrying case.

What would I need to make one of these into a 24/7 last.fm/pandora music streaming machine?
I got a job just in time to buy a model B when they come out.
We finally have an OP that knows what he's talking about rather than a random tech illiterate
Considering buying this, once i look into the chipset more, then i can probably pick up a mini wifi module/bluetooth and attach it along with possibly other mods, in a slightly bigger case, maybe adding a bigger battery and a touch screen, it would require some work though, atleast i dont have to worry about accidentally burning components at 25 dollars :D.
Will this thing be able to run Dwarf Fortress? I'd play dwarf fortress all year until death.
No, and even if you could the framerate would be atrocious.
okay
Too much power, would blow fuse, would need to use powered USB hub, probably doesn't have Linux drivers, if it does, they probably don't compile on ARM.

How do I know if a certain device would blow the fuse?
[QUOTE=leontodd;34850885]How do I know if a certain device would blow the fuse?[/QUOTE]
The power draw.
It's got a couple of polyfuses onboard.
[QUOTE=Van-man;34850924]The power draw.

I doubt they are fuses, they are most likely PTCs aka "resettable fuses". If they are PTCs, they will only shut down the USB controller temporarily

PTC AKA polyfuse
[url]https://en.wikipedia.org/wiki/Resettable_fuse[/url]
In short, same shit, different name.
It has fuse in the name, it's a fuse.
Yeah, they're resettable fuses.
It shuts down the device, that way you know you went over 1A and don't damage the device.
