With most new HD tvs these days coming with only one dvi port on them, A affordable dvi switcher would be very handy. Iv ordered one of those new Samsung dlp tvs and I know I have more than one dvi source but know way to hook them all up. Most of the big players are supporting dvi even the new sony and samsung directtv and ota hd recvers support it so its here to stay and would be a nice new product.
