Re: Known to work SD cards. Please add yours !

I am testing the 32Gb Class 10 Samsung MB-MSBGA/EU on a BeagleBoard just now and it's really fast, and it's also very cheap. Could you give it a try to see how it performs on the RPI?

Re: 4 USB, no ethernet future version of Rasperry PI

<t>Nice idea, but depending on the device it would be neccesary to use a powered USB hub, so in that case you could get your table with two extra wires. If you plug a Wifi card you can save the Ethernet wire, so you have the mouse and the keyboard wires, and a free USB connector to plug for example ...

Re: 4 USB, no ethernet future version of Rasperry PI

Replacing the ethernet connector with a 2 USB connector it would be possible to plug a Wifi USB card, a mouse, a keyboard and we would have 1 free USB for example to connect a printer or a webcam. Wifi USB cards are cheap and Wifi is also very common in Europe schools.

Re: An OS for the R-Pi created completely in assembly

<t>I think it could take tens of years for a person to write an OS for a device so sophisticated as the RPI processor, that's the reason why an open source OS is being used to run it instead of writting one from scratch.<br/> I think it would be better to optimize as much parts of Linux as possible ...
