NI,
To me portability is an issue too, we really like the portable Apple computers, and to drag along another box is not an option. It is bad enough as it is with the multimeters, oscilloscopes, loggers, power-boxes etc. This speaks for the GPIB-USB solution, a cable, a driver, and that's it.
As for the MacOS X this is the future in the Apple world, and Apple is big in education. And afaik the only OS developer with clear focus on educational solutions.
