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.

PS. ( WRT ) 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.
