Also, the Blu-Ray rips you've downloaded have been compressed, so that they've lost information retained on an actual blu-ray disk. This includes both image quality and bonus material. Besides, the DVDs you pick up in a store have much lower quality picture, because it uses an older, less efficient codec. However Blu-Ray equipment will get cheeper, and Blu-Ray burners will get faster as time marches on. Finding the right time for getting it might be difficult.
It might be the standard for movies, but how many people do you know that store any kind of data on a Blu-Ray disc that's not a movie? It's ineffecient to even use DVDs/CDs for data storage/backup.

Also, if you actually do buy Blu-Ray movies, then go for it. But I never buy movies, and have never needed an optical drive.
