Anyone who thinks size is all that matters should head over to the Doom9 forums and ask the experts why more space doesn't necessarily translate into better quality. You'll be told how quality depends on a lot more than raw bitrate, and how codecs max out above a certain level.

Being able to get content from other countries can come in quite handy, and unlike the situation we had in the early days of DVD, region-free Blu-ray standalone players are limited in number and unreasonably expensive.

I care about what I can do with movies I pay good money for (think fan edits, format shifting, creating back ups, etc.) so I will be staying away from Blu-ray.
