don't get me wrong or anything, i would love to see the burnable bluray drive inside of the MBP as BTO, but for the price and lack of speed in the drive it would hardly be worth it. for just a 2x burnable drive, (probably not even RW capable) you are looking at $700 at least, from apple anyway, we all know what they are like. that drive would take way to long.
according to wiki...
if you are burning a full 50gb DL bluray disc, that is going to take around 5hours to burn. unless you are fine leaving it on overnight, there wont be much time in the day to just let it go. for backup purposes only wouldnt it be much easier (and cheaper) to have a nice big external HD to backup to while you are away on trips etcetc?
i donno thats just how im thinking..
When I say backup purposes, I mean should the desktop Blu-Ray writer die, and I really need to burn off some material. Don't forget though that not everyone wants or needs to fill a full Blu-Ray disc. Each to their own though
