This discussion is an interesting parallel to a letter that appeared in last month's Cycle World magazine about air vs. liquid cooling in motorcycles.
The main advantage put forth for liquid cooling over air cooling in motorcycles is the ability to route the cooling water directly to the components that need it most rather than hoping that some of the fast-moving air makes it to the cooling fins of an air-cooled machine. The situation in CPUs is arguably worse because you have to artificially generate the fast-moving air that is readily available in a moving vehicle.
It seems to me that by building water jackets for CPUs you are already missing out on a great deal of theoretical efficiency available from water cooling, which would be to design the chip with cooling passages built in. Most of the projects I have seen are pretty similar to this - low budget efforts that obviously wouldn't take chip design into account.
I did a brief search and wasn't able to find much beyond these types of projects. Does anyone know details about projects out there that involve liquid cooling from the start?
As an employee of an automotive company, I am all too aware of crash test standards in my work. Modern cars are as safe as they are because they are sujected to repeated tests under numerous conditions.
How about an open-to-the-public and televised Segway crash test session with Dean Kamen featured as both a rider and an obstacle. For starters:
Dean Kamen aboard Segway vs. phone pole Subway Jared aboard Segway vs. stationery Dean Kamen
If the Segway is as safe to pedestrians and riders as Dean Kamen says it is, let him risk his own ass to prove it.
As several people have said, the SD card allows the flexibility of adding the features you want that don't come standard. However, as soon as this list grows to more than ONE, say a SD memory card and a bluetooth adapter, you have to start swapping the little buggers around and juggling files appropriately. If, for instance, you want to send a file from an external memory card via Bluetooth, you'd have to copy the file to the device memory, swap in the bluetooth card, wait for it to be recognized, and then send the file.
This kind of implementation hampers the ease of use that Bluetooth can (but frequently doesn't) have.

...We need "Google" girls? They could have those neat t-shirts with the appropriate number of OOOOs...
This is getting a bit OT, but in case you were interested, the sum of the numbers on a Roulette wheel is also 666...
