Most important bit of insight in this article: no ECC (Atoms are consumer CPUs and as far as I can tell Intel is very rigorous about limiting ECC to official server chips).<p>ADDED: in his reference post (<a href="http://perspectives.mvdirona.com/2009/10/07/YouReallyDONeedECCMemory.aspx" rel="nofollow">http://perspectives.mvdirona.com/2009/10/07/YouReallyDONeedE...</a>) he says "<i>All AMD processors whether server, embedded, or client have ECC. All ARMs have ECC.</i>" and makes some other very interesting comments,
My #1 question in this case is how do the various virtualization technologies scale out. I suspect they don't very well, but if they did, this obviously would be a huge win.
