Hi Luisa, in my research on home computers from the 1970s I haven't found that the idea of personal computing was always represented as something new and incredible. Computers were familiar to people (many of whom had a negative impression of them as instruments of institutional control) and it wasn't clear what needs a home computer would satisfy. One persistent question in articles about home computers in magazines like Esquire was: what are you actually going to do with it? A frequent answer was that you would use a computer to learn how to use a computer. Probably the most common use for many people who bought a computer for the home was playing games, which wasn't so different from using something like an Atari VCS. In advertisements for home computers on TV, you will find some of that "new and incredible" tone -- they're selling a product, after all, though what they're selling is as much a platform for games as it is a computer for programming or other more "productive" uses. The "Atari brings the computer age home" campaign would offer some nice examples of this, and some (in poor quality) are on YouTube.
