I'm getting a new iMac shortly, and still use old luddite technology (optical drives). As it looks like I can get a blu-ray reader/writer for not much more than a SuperDrive I'm leaning towards that option. So, in your opinion, which of the blu-ray options is most compatible? The things I'm interested in: * works with iTunes to rip CD's, backup iTunes purchases * works with iDVD, DVD Studio Pro, et al to burn DVD's * works with Toast to burn blu-ray disks * works with DVD Player to view DVD's * USB 3.0 support * Bootable Some things that would be nice to have but not essential: * uses a single USB port for power and operation * can use additional application to view blu-ray disks * looks nice Some things I've not quite got my head around: * how many formats do drives/disks come in? Seems like there are at least two configurations, one holding more data than the other. Support for the larger format disks would be useful if possible. I think that's about it. Any other input is welcome.
