Not true. Also, USB sucks for multiple reasons (extensive driver headaches, unreliable connections, bad platform compatibility (cf. driver headaches))
Fair enough, its only as good as the platform and drivers its build on.
But USB is everywhere now. ok you can buy a GPIB PCI card, used as low as £30, but some are going for £80-£100, seems to be even more if you want PCI-Xpress. USB-A to B cable, most of us have floating in a drawer somewhere, practically free.
When was the last time you saw a GPIB card on a PC - scrap that, you probably have one!
Ok you can get USB to GPIB converters too, cheapest I search for was £78.
Anyway this is not to put off houkensjtu of his purchase, looks like a good score.
