Mostly this. I wouldn't pay more than $30-40 for a Blu-Ray burner. I'm willing to wait 5 more years if I have to. Even if I got it, there's no proof that I'd actually end up using it.I waiting for Blu-Ray drives to drop a bit. I only use mine to install OS.
Flash drive, cloud, DropBox, STEAM, Battle.net, email, wireless network, streaming, and many other sources are still available for me to use.
I'm still using my BenQ DW1620 IDE drive from Spring 2005. I refuse to upgrade because most of the DVD drives compared to it today are crap(and no, I'm not talking about comparing "burn speed"). If I can find a black BenQ DW1640 SATA drive for cheap that still works and isn't all beat up from a reliable seller, that will be my ultimate dream.
In my new system since Fall 2009, I can count on one hand how many times I've used my BenQ DW1620:
1.) Used to install Windows 7.
2.) Used to burn an African music CD my mom wanted to give to her friend.
3.) See #2, only this time a different artist and album Disk 1.
4.) Same artist and album as #3, Disk 2.
