I always put optical drives in a PC, even if it's just a $15 DVD combo drive. Pennies compared to everything else that goes into a system, and it's still convenient for those times (rare, perhaps) you need it. I have a blu-ray burner myself, since My PC is connected to two TVs as well.
But I hang on to old technology longer than others. I still kept a floppy drive around until about 2006.
