Why should I buy a $500 machine only to turn around with it being useless in 1-2 years to buy another one WHEN downloads take off? This is a valid reason, that many of the blu-ray zealots just can't get a grasp of. There is NO stopping digital downloads.
Where did you get the idea that the availability of downloading negates the availability of disc-based software?
We've been downloading music for years. We can still buy CDs and CD players.
