The advancement always lies in making a technology more practical in this industy.

....... numerous fans and bulky water cooling systems are coooool.

How is this new?  The only thing they did was shrink the process.  This is the fundamental principle behind any refridgeration system.

pretty cool.  If they make it affordable and simple, I can't wait.

I gather that by using such small channels they can allow the liquid to actually boil. In current systems, the coolant just heats up. This means more heat is transferred.

Actually in refrigeration system the liquid evaportates to a gas and this allows the system to cool, it is then pumped outside of the cold area, and changed back into a super heated gas, that is then pumped back into the system to evaporate and cool again, it much more efficient then boiling.

We're not really talking about refrigeration systems though. Yes, air conditioning/refrigeration uses vapor compression cycles. But these use CFC/HFC refrigerants that boil a very low temperatures.

Current PC cooling systems just heat fluids below boiling. This system is circulating fluids (I imagine not an actual refrigerant) into a component to boil (evaporation is actually a spontaneous and slow process) quickly by effectively exposing an increased surface area to heat.
