If you go to expansys to order the 1.86 GHz version of the OQO, you will find that the expansys is showing that product has been discontinued. This makes us wonder as the product is barely few months old. This can only mean one thing: OQO is going to launch the revision of its flagship model. It can be that OQO is preparing the revision of model 2+ with Intel Atom 2.0 GHz (Z550) instead of Intel Atom 1.86GHz (Z540).
It may be noted that the power consumption of Z550 is same as Z540 even with the speed jump. Also, it makes sense to equip the flagship model with the best available mobile processor.
