The E1xx series are NOT "a PC in a wierd box". They're embedded platforms for embedded applications involving SDR. The on-board CPU isn't in the same league as most desktop multi-core processors, and even though it runs an embedded Linux, it's not just a "tiny desktop machine". The intended use for these platforms has always been that heavy-lifting signal processing would happen on the FPGA, so most users of this platform are adept at implementing algorithms on the FPGA, with the CPU largely acting in a "supervisory" role. Now, it turns out that there are some applications where most of the signal processing will "fit" on the embedded CPU. There are ports, for example, of OpenBTS to the E1xx series. But asking it to do signal processing *and* GUI user-interface work at the same time is asking a *lot* of that single-core ARM CPU.
