We've just noticed that the average price of regular desktop dual in-line memory modules, commonly known as DIMMs, is almost comparable to that of the smaller SODIMM - Small Outline DIMM - components.
It may therefore be time to consider whether a single memory form factor doesn't make more sense than having two different ones - one for SFF and laptops and another for desktops and servers.
One of the main reasons why desktop & laptop memory parts have reached price-parity is because demand for laptops and small form factors like tablets has caught up with that for non-mobile devices.
Additionally there's the smaller but not negligible bill of material which is slightly lower for the SODIMM part, which means smaller PCBs and less connectors (SODIMMs are around half the size of regular DIMMS).
There are also some compelling reasons as to why SODIMM, just like smaller 2.5-inch hard disks, should replace their desktop counterparts.
Having a single memory type will mean even cheaper prices as economies of scale dictates pricing and allows manufacturers to stock just one format and reduce exposure to price fluctations.
Adopting SODIMM will help to reduce the size of motherboards (and their corresponding bill of materials) even more; SODIMMs are already popular in mini-ITX and other small format motherboards and there's no reason why they shouldn't become the norm.
SODIMM allows for denser memory configuration as manufacturers build on experience gathered from laptops and ultra compact form factors.
