That is my (sad) impression as well, from some limited testing. It
seems the Duo Core can outrun a G4 even when translating PPC machine
code on the fly. Ouch. That of course means that a MacBook (neé
iBook) will quickly become the cheapest fast mobile IDL workstation
(unless you need monster 3D performance), when the re-compile happens.
Less than $1K with academic discount:

By the way, I've successfully created double-clickable OSX IDL
applications using the IDLVM, and it even associates file extensions
(saved objects) with this application. I do it using a small glue
script together with "Platypus" (http://www.sveinbjorn.org/platypus).
Works very nicely.
