"64-bit versions of Windows, Mac OS X, and Linux now
are in widespread use, and software for the operating systems is
following suit. So it may seem a bit backward that Adobe withdrew
its only 64-bit version of Flash Player.
But don't take the disappearance of Adobe Labs' experimental
64-bit Flash Player for Linux as a sign of things to come. Moving
its widely used browser plug-in beyond the 32-bit era is a "top
priority," said Tom Nguyen, Adobe's Flash Player product manager,
"However, Adobe isn't committing itself publicly to a delivery
schedule. And if it doesn't move with some alacrity, it risks
inflicting broken Web sites on computer users who do make the
64-bit shift with their browsers."
