I have successfully used a hauppauge wintv usb under linux (and at least one other person on this list has this working too). The two remaining problems with usb tuners are 1. the linux driver doesn't support the compression of the device yet (i.e. low framerate <10fps usually) 2. even if compression would work it's cpu intensive and still not as good as full pal video via pci.
seems (i didn't test it) the usb-bt848 drivers now support compression in a beta state: http://sourceforge.net/projects/usbvision/ and http://www.emuit.com/webcam.html
but X is right: if you want to use video input on your laptop: go for usb, in every other case : use pci
