First of all this commercial is from 1985, a time when nobody actually knew the limits of the Amiga let alone guessed that without Amiga Battlestar Galactica 2004-2007 would never have happened (the CGI is all Lightwave, which exists only from the profits of Digi-view and that only exists from the leftover unused sections of the A1000 chipset which became HAM mode). This is a time when it was ludicrous to expect your computer would be simple and friendly, play any sound you could possibly digitize and display any animation or still image with an unheard of level of realism possible on any other personal desktop computer.
Secondly it is clearly going to be subject to the look and feel of the 80s, which frankly is Miami Vice or Manhunter etc etc so you can hate it as much as you like but this is what good adverts looked like in the 80s, a bit of sophistication.
But so what if it doesn't show someone using a computer, if the person didn't look like a spotty geek it wouldn't look real and such a thing on screen will not align with their target market (professionals or bored yuppies who need the best not a chumps breeze block calculator).
So in essence it is a commercial designed for well appointed successful individuals who don't want some nasty piece of tech but a beautifully elegant looking and friendly operating environment computer. The fact that it is the best creative computer ever created out of the box is nailed with a single line too, for once it is a truthful statement.
We were not the target audience beware, I bought it based on tech specs alone as did most of us coming from earlier 8 bit micros, but the kind of people who that visual style is familiar and who do actually want to do creative things on computers. And let's face it the A1000 on the pedestal looks gorgeous.
It's not as memorable as the C64 elephant adverts sure but it gets its point across perfectly in both intent (a creative machine not some piece of crap spreadsheet) and as soon as you use an A1000 and a Mac 128k/SE together only an idiot would choose that Apple monochrome P.O.S.
Commodore's problem was we didn't get classy ads like this outside the US and then we got none at all in 1986 while we were waiting for that other suicidal business plan "drop all promotion on the 1000 for a year while we wait for technically identical A500 24 months after the 1000's launch"
In essence they were going for lawyer's offices and art studios and animation groups etc and this fits in perfectly, the kind of offices they wanted it in were just as ostentatious and ludicrously expensive in decoration.
