We have two new (3-4 months old) HP Pavillion dv8t PCs, both running Windows Ultimate 7 x64, and BOTH having Acrobat X Pro (v 10.0.1) and Adobe Reader 10.0.1 (all software is updated daily.
On BOTH PCs, I see Reader shows this file just fine, while Acrobat does a miserable job?

What do you mean by "miserable"? I'm looking at your file in Acrobat X Pro 10.0.1 on one of our slowest machines (Core2 1.86, XP32, 3G ram) and it renders just fine. I can scroll through the document as fast as I want, there's no paint delay on the contents, I can search it and zoom smoothly.
Also checked it on one of our Win7 x64 workstations, same result.
