Movie buffs and TV fans want to know whether they should invest in Blu-ray technology--such as whether they should buy a portable Blu-ray player for the kids and stock up on Blu-ray movies, which typically cost more than their DVD counterparts (for instance, Transformers: Dark of the Moon will cost you $20 and the recently released Star Wars: The Complete Saga is $140).
