Minimum machine specs

This is a serious question, as my Macbook Pro duocore i7, 16GB, 1TB hard drive is not up to the simple task of browsing 36Mpix photos. ON1 is not responsive for seconds, keystrokes are ignored (like clear rating `), the process settings are not applied, and the battery dropped 10% after just viewing 20 pictures. And I'm not even talking editing. C1 is blazing fast in browsing, and there's not even a distinction between browsing and editing there.

So, seriously, ON1, what machine do you recommend?
