My machine is an 800 Meg Pentium with 512 MB of Ram and an 8 GB SCSI disk. I'm using a cable connection and this might be why it's working so "well". It works snappily enough without distortion from Dectalk and some of the audio streams work great. I think there is a problem with the distributed mplayer binary in that it won't decode some audio streams. Also, the Freedombox Media Player doesn't close when streams of voice messages are finished. Text messages go through snappy and fine though there is occasionally instability that causes Freedom box to crash--sometimes leaving X running and sometimes shutting it down. Haven't played with chat. A stream that works fine is the BBC world headlines section of the news and talk radio section.
