That board is slow and it only has 256 MB of memory, but also requires no cooling (complete silence) and if you consider that all devices are connected over wireless, speed is good enough for file sharing which is its primary purpose anyhow.
However, market is wanting more powerful processors and Geode is going to history. They do say that they will produce it while there is need, but any company that still uses them will start searching for a replacement. The end is imminent.
Since only requirement for my server is low noise (passive cooling and 2.5″ HD), I already see replacement – MSI WindBOX.
