Quote - I have three items which I cannot get to work under XP64 - a Palm device, a Zune mp3 player, and  an HP printer that's about 3 years old.  The Palm and the Zune both have to be synced on the 32-bit side of my dual-boot setup -- and the printer will only print on the 32 bit side.

However, the Zune .mp3 player is supposed to be compatible with Vista 64.  I'm not sure about the Palm.  There are no 64 bit drivers available for the HP printer -- neither XP nor Vista.

Software-wise, I haven't had any problems at all under XP 64.  In fact, everything runs better than it does under 32 bit XP.

I haven't liked Vista since it first came out.  But now they seem to be showing some movement towards improving it.  Plus -- as others have hinted -- hardware & software manufacturers are gradually catching up.  Vista is beginning to show signs of life, I think.  It's taken awhile to get there.

Palm does not support 64 bit... People have been complaining about this for a long time now.

I find it hard to believe that the render engine is 64 bit in OSX when nothing else is...
