The potential pitfalls of Blu-ray

We're good sports. While Blu-ray has "won" the "format war", there are still a number of areas where it needs to watch its back as this Digitimes Research data has revealed. What are they? Let's make a bulleted list so it's easier to separate them.

• Not all game consoles support Blu-ray. With DVD, every game console decided to base its hardware on the disc. However, the Wii isn't fully HD and the 360 probably won't jump into the Blu-ray bandwagon, so it's all up to the PS3 to shoulder the weight of Blu-ray. But hey, add-on drives to the 360 aren't an impossibility.
• In-car audio/video equipment is basically incompatible with Blu-ray. Not that we'd really recommend you playing a Blu-ray video in a car anyway, but DVDs work fine. You need a screen double the size of those available in cars to even get a proper resolution.
• As far as backing up stuff on the PC is concerned, Blu-ray isn't that necessary. DVDs and CDs cover the small stuff while external drives are useful for backing up the big stuff.
• The same goes for business use in terms of backup. Blu-ray isn't competitive enough with the UDO market in the business industry.

They conclude saying that Blu-ray is useful only for watching movies and playing PS3 games. It's a decent list of worries, but are they really big worries, or just making mountains out of mole hills? Let us know your thoughts.
