YES,---I also use SanDisk 4GB CF cards - and I have the firewire CF card reader.
But, the advantage of the PCI plug-in reader was that there was one less cord and one less box to pack for a long trip by air - or to lose in a motel in Montana. Surely someone can find a way to have a CF width on one end and a 34/ width on the other end.
No wonder that more and more new cameras - including professional models - are going to Secure Digital.
This is one more reason to keep my credit card in my pocket when I look at the 17 inch MacBook Pro - that and a working air/car power plug with a MagSafe connector. My 15 inch AL PB will do fine for a bit longer - and Photoshop CS3 is not out yet anyway.
