It could be a mock, however, Amigas can natively be synchronized with teevee cameras during shooting, which was why lots and lots of computers on teevee during the 80s and 90s were done with Amigas. In other words, it is easy and cheap to make a display using an Amiga and a CRT that will synchronize and be perfectly viewable on the show as it is being taped.
Some Amiga ports from the *nix world also could use its file structure, though it isn't common. Well it sort of was back in the early days, from looking back at my Fred Fish (may God rest his soul!) disk collection. But, even if it is a mockup, whoever mocked it up had Amiga experience, as in the drawers 'workbench' etc. in the screenshot, also the dir structure C, devs, etc. as mentioned earlier here. A welcome break from the Dells and Apple Macs you see all over the show normally. (first few seasons it was all about the Macs, then Dell came in this season. Wife's into this show so we watch it together.)
She got the chipset names wrong, but who cares. Angela is still super hot, and her mentioning the Amiga just makes it even more so :-D
