On the 64-bitness.... Those who need it, know why, and how to use it... those who don't know how, or why, at least still get to keep some bragging rights. ( Think WindowsXP 64-Bit ) BTW: Panther has some 64-bitness to it... those in the know, know how to use it . Second... I would be curious to hear from those with the Tiger preview if DVD+RW disks are finally handled the way the format was intended ( i.e. Floppy/hard disk like ) . Max.
