I still don't understand why you're dual booting.
Use a VM like Parallels or VMWare Fusion, or even VirtualBox (free!) to run Windows right from OSX. You don't have to dual boot, and the performance will be just fine for Adobe Reader.
The problem is not Apple's, but Adobe who made a totally crappy software solution for OSX.
However, why don't you just use the built in reader in OSX? You can read PDFs, search them, write annotations etc. they doesn't look different than in Adobe Reader. That's the whole idea with PDF They look the same regardless of the viewer you use.
I was thinking if dual booting anyway because my university has free licenses for SPSS for Windows, but not OSX. Between that, the PDF issues, and what I've read about performance for gaming not being that great when trying to run Windows via Parallel or Fusion, I think dual booting is the way to go. Also, it's free compared to buying Parallels.
Also, I read VirtualBox is not that great compared to Parallel or Fusion.
