S'okay, said it was just my opinion
Blu-ray has doubled its market share since this time last year. I think it's now at 7% (I forget if that's discs or players).
Pretty sure that's players, average of 3 titles owned per player, waaaaayyyy behind DVD uptake at the same point in life cycle.

"The interest in upgrading to high-def players is only mild, and Blu-ray ownership won’t hit 25 percent of US households until
the end of 2011, as reported by Reuters/Hollywood Reporter."
"Disc ownership is down among Blu-ray owners compared to first-time DVD owners, who owned nearly 30 titles at the same point in the adoption curve, according to the report. Blu-ray households own an average of three titles a piece."
"According to recent research from Interpret, LLC, Blu-ray awareness has hit 60 percent, but hardware penetration is still low. The Reuters report argues that Sony’s PlayStation 3, which has an embedded Blu-ray drive, isn’t doing the job."
"Plus, since the vast majority of Blu-ray players are in homes because Sony has embedded them into the PlayStation 3 video game consoles,
many consumers don’t seem to care that they even have a Blu-ray player."
As far as relying on what Wal-Mart says for how the world works, um, don't. I have never bought a DVD player from Wal-Mart, nor much else in the past decade. I'd much rather go to a place that 1) I don't hate, and 2) sells more eletronic equipment. I just bought a new BD player at Best Buy and don't have to pay interest for 18 months plus got it $50 off.
I don't buy electronics from Wal Mart either, but they sell a ton of movies. More than just about anyone.
As far as this holographic disc, it's all rumor and speculation at this point.

To go with that, these "high-speed" laptop HDDs aren't HDDs. They're SSDs, and they're still WAY more expensive per GB. A 500 GB HDD is about $100. 375 GB worth of BDs are $80. So the discs are about a wash financially, but the SSDs are way more expensive.
I was actually thinking of the 500GB 7200 RPM models. Just a few year ago, 60 GB was a good size for a laptop. Also, what do think would be easier to carry around, a HDD, or 375 GB worth of BRD's in Jewel cases?
