I made the switch last weekend. Installed 64-bit Vista and reinstalled all my applications. To date, I’ve run across exactly ZERO compatibility issues, except 1, for which the vendor provided a 64-bit compatible version of their software.
All I can say at this point is that it just works better. Things are snappier. As Paul Thurrott said in a recent Windows Weekly podcast and blog post, 64-bit Vista is really a non-event as far as having issues goes.
My Dell D630 also now supports 4GB SO-DIMM’s, so I’ll be upgrading to 8GB when prices on those puppies comes down (somewhere ~$600 each – yikes!).
Lovin’ the “I’m a PC” campaign from Microsoft, BTW. Finally, Microsoft got it right.
