Five high-tech terms to understand before shopping
Blu-ray is the recent victor of the Blu-ray vs. HD-DVD format war. That format war was very similar to the VHS vs. Betamax format war of the 1980s.
Both formats wanted to replace the DVD in the same way DVD replaced VHS, and both were offering pretty much the same thing DVD did back in the day with more space for content and better picture and sound quality.
Blu-ray has absolutely delivered on its promises with a beautiful picture and over six times the storage capacity of regular DVD. However, it landed at a really interesting time. More and more people are wanting movies delivered digitally just like their music. Also, old Blu-ray players do not work with the latest 3-D formats with the exception of the PS3.
Now consumers have to consider whether or not Blu-ray will even be around for any length of time, and if it is, should they invest in the more expensive 3-D technology?
Consumers are now left with a tough decision this season, but then again, that's the nature of technology.
"Stick with what you need, not just want," Siegler said. "Tech updates so quickly that in a few months you may find yourself filled with regret about a purchase unless you really needed it."
