Uhm, no thanks? I'd rather keep the 13" in the lineup. I get the Airs, but why the 13"?
The 12" is fan-less and it seems there are possibilities for a quad-core in an upcoming 13".
EDIT: Or did you mean you're hoping for a 12" in MBP shape with a more powerful CPU (e.g. quad-core) and more ports? If so, I'm in.
Well, in my original plan, I'd be killing off the 13" MBP. If the new "real pro" line-up would be available in 13-15-17 inch formats starting with modest specs, that would replace the 13" MBP. With the Xeon and other fanciness as options.
Just thinking of a way to simplify the line-up. I know the Jobs days are long gone, but we currently have 7 (!) base models: MB-2xMBA-2xMBP13-2xMBP15. That's just horrible. I think it would be easier for Apple to set up the logistics to ship upgrade SSDs and memory to the stores than to manage all of those SKUs.
