Raspberry Pi 2 First Slice
I purchased a SanDisk Ultra PLUS 16 GB Micro SDHC UHS-1 card for ~$16.00. It claims speed up to 48 MB/s. That is about as cheap and good as they come. Usually cheap and good aren't found in the same item. All you can see in the picture is the tiny black tab of the memory card sticking out at the bottom edge.
The raspberry Pi 2 Model B 1GB is marketed as being 6X faster than the original Pi 1. For more information check out https://www.raspberrypi.org/
I agree. It is MUCH faster than my older Pi 1 version. In fact it is so fast I believe it could serve as a main computer for my Ham Radio station. It's no rock crusher but it runs as good as my Asus netbook. I am not saying that is my purpose for this machine. At first look here it appears it is a good Linux machine for writing code. It has an excellent screen display using (HDMI) output and it uses any standard keyboard of choice.
At this writing I would pick the netbook over the Raspberry for overall ease of use as a conventional portable computer as the netbook has the screen and keyboard all in one package. The benefit of the Raspberry is it is equal in speed to the netbook and is so open for experimentation and modification - and at least 10X cheaper in cost.
Pi 2 is a great little machine for a very low price. It fits in well with the Basic Stamp and Propeller single board computers I have worked with for special purpose dedicated computing, but with a much more powerful on board I/O capability. Hobbyist hardware hackers never had it so good and that includes me.
