Linux Software for the Raspberry Pi is quickly moving forward. Beyond the several core Linux distros, another couple dozen systems are available, with NetBSD, FreeBSD, and Chromium imminently stepping into the mix. (Ubuntu will not join them as it requires ARMv7 and the Pi is ARMv6). Two dozen programming languages are available, including Python, Perl, Java, Ruby 1.9.2, BASIC, and more. Since the Pi is a full fledged ARM computer, it should run nearly any ARM app within its system requirements. See the RPi Wiki or Foundation website for more info.

I wasn't talking about your mother, now was I? The fact is that USB 2.0 HDDs are terribly slow, limited to about 35MB/s speeds, and as such boards like this still wouldn't work for quite many people. Also, if we were talking about your mother she wouldn't need a quad-core CPU or GPU for mail and browsing anyways.

No, but you also weren't talking about the average user, either. Instead, you came to nitpick and bizarrely quote data transfer rates. That's what you came to discuss instead of commercial applications of cheap hardware. Good for you, have a star.

What the hell? Why are you so terribly defensive the moment I mention possible bottle-necks? With a SATA-port the CPU wouldn't have to spend so much time idling when trying to read stuff from an external storage device, meaning a nice increase in performance, and well, plenty of people still DO have a need for larger storage devices due to family photo albums, home movies, rental movies, music collections and so on and so forth. That IS a "commercial application of cheap hardware."

Though "terribly slow" probably goes too far? Maybe "slowish" ...and OTOH quite enough for many other usages - reasonably comparable to 100 MBit Ethernet, when the little board is used to serving something over it.

PS. ( WRT http://www.osnews.com/permalink?543124 ) and with USB, CPU hardly idles when reading - USB is more CPU-intensive; maybe USB2.0-only is not such a bad thing on meagre CPUs.

AFAIK, it is only USB 3 that introduced proper use of CPU interrupts for signalling, while previous releases required constant polling by the OS. Combining that with the larger packet size, a USB 3 stack might actually end up going easier those low-performance chips.

At least if OSs and devices supported it well, which, considering how well Linux 3.2 can react on dmesg and elsewhere when I plug something into my USB 3 ports, is far from a given.
