Intel Cedar Trail-D 2011 platform to use DDR3 SODIMM
 

it looks like Intel will get rid of DIMM support for future Atom desktop platforms, popularly known as nettops. The one that comes out in January, codenamed Pine Trail-D, will have support for single channel DDR2 memory DIMM modules, but the one that will follow in 2011 supports only SODIMMs.

This will increase the price of the system as SODIMM, a memory standard traditionally used in notebooks, is somewhat more expensive.
