I agree, x64 Vista is being well support by Microsoft and Hardware Vendor's; x64 XP is the unloved middle son that still has many problems that will probably never be fixed.
Unless you really need more than 3GB of memory though your probably best sticking with 32bit right now for a workstation OS, certainly I don't see anyone needing more than 3GB for gaming or pretty much anything else, although inevtiably that will change over time.
On big application servers the need is obvious and urgent as the 32 bit limitation really was a bind but that's only for stuff like Exchange, SQL, Citrix etc. However for the workstation this is not the case.
