Their Conclusion? I have had the opportunity of reviewing a multitude of items over the past two years and the EFiX is one of the most unique and exciting products that I have encountered. It works as advertised and could not be any simpler to install and setup. Using a store bought copy of Leopard, I was able to get up and running in under an hour. By using recommended hardware from the hardware compatibility list the user can build a Mac as powerful as even the highest end Mac Pro models. The EFi-X USB V1 seems to be an evolving product as the makers add new features with each subsequent firmware upgrade. If you want to build a machine capable of running OS X, Windows and Linux on one platform, then the EFi-X USB V1 is the solution. Pros: Plug and play simple Works as advertised Firmware being constantly improved by makers Obviates the need for hacks when installing OS X on a x86 system Can triple boot OS X/Windows/Linux environments Cons: Works with only certain hardware
