I don't have a big collection of DVD's I'd have to replace (don't really understand that concept anyway). I rent mostly, but the few movies I buy I won't have a problem paying 25% for Blu Ray. I have a hard time believing the pic quality isn't much better. Going from DVD to HD DVD on the same player and same movie was a big difference to me. My mom really wants the thing, so as usual, "mom's always right"
