How about every Sony Vaio (except their netbook) and Toshiba Satellites Pro (starting at 800$) shipping with FW (a.k.a. i.Link or IEEE 1394) standard.Name a single PC that comes with FW standard - there are none.
And these were just the first two brands I checked. I'll bet Lenovos and HP's produce their FW series as well. But you probably won't find IEEE 1394 on sub $500 Acers.
