Apparently I should be speaking with friends back in Oregon more often. I always knew my friends or their parents worked at Intel, but haven't thought about ever asking them which groups they work in. Yeah, I know, it's pretty lame of me. So I did some poking and prodding and promised some things I probably shouldn't have to get this info, but I think it's worth it in the end.
I obviously can't reveal my source, but I can tell you that He/She/It was directly involved with Apple on the Intel-based Macs. He/She/It didn't give me much dirt unfortunately, but He/She/It did confirm without a doubt that sub-notebooks will be announced at Macworld.
