Thanks for clarifying this up.  I didn't realize 1080 was 1920x1080.
For some reason, thought something like less then 1280x1024.  I hope we
can trigger a switch within the box to show 1024x768 on live playback.
I'm assuming we can at this point.

I don't plan on upgrading for still another few years.  VIM still seems
to run find on my 2x750P3 box here, as well as my P3 1Ghz laptop. :-/

I'm sure I'm not the other one who's only need is VIM. But, I'm guessing
you had to buy the 2Ghz for Emacs. ;-)
