What is the main difference between the Intel Atom Z series processors used in the Acer Aspire One 751 and the Atom N series in the Acer Aspire One AOD250? Performance-wise, which is better?

The Z-series Atom processor are smaller chips built for Mobile Internet Devices, while the Atom N chips target the larger Netbook segment. The former uses less power and hence improve battery life, while the latter has marginally improved performance and cost less than the Z series processors.

So to answer your question, the Atom N CPU is slightly faster than the equivalent Z version. Since the Acer Aspire One 751 has a larger screen than the Aspire One AOD250, the energy savings using the Atom Z is unlikely to translate into better battery life. However, I would still pick the 751 over the Aspire AOD250 for its larger display and better keyboard.
