I'm persuaded.
I'm using Vista x64 and, having spoken with others, ACR 5.x sounds worth the upgrade.
Just ordered it!
Thanks for the feedback.

ps. As someone who uses a Hasselblad H3Dll MS 39Mp, I can sympathize with those who'd like their camera supported by ACR. That said, anyone who has seen a 4 shot file shot using Flexcolor in Reproduction Mode has been blown away. But, I digress............
pps. Why do I get a reminder email for EVERY new post to a thread rather than just one, as on most internet forums?
