If you were wondering about Blu-ray.....

Just as VHS won the video tape battle over Beta, the Blu-ray Disc reigned supreme over HD DVDs. So yeah, the graphics are amazing, but what's the big deal? Well, first off it's not just video, the audio quality is much better as well. While CDs, DVDs, and Blue-ray discs are all optical disc formats which utilize lasers to read the information written on the discs, Blu-ray uses a blue-violet laser of a shorter wavelength which allows you to focus the laser spot with more precision. In a nutshell this allows BDs to hold more than 5 times the amount of information than a regular DVD. That's what it's all about, the storage space. This is the technology that brings you true HD movies and HD gaming experiences to your door.

DVDs are not going to disappear over night, and quite frankly they still get the job done for me, but it may be worth your while to start making the switch. The prices going down on BD players, and I am even finding ones for under $200. The movies themselves are about $30 a piece, and when you are paying $20 for a regular DVD, it's really not that bad a deal...... and there's always the PS3 option so you can get the best of both worlds.
