It looks to me as if TheSimpliFire figured out the answer and stated it in the comments to the OP, but that was several hours ago so I assume they're not going to make an actual answer at this point. (Maybe they were just guessing?) So let me fill in the details, or at least as many as I've been able to find; I'm missing a few.
The word we are looking for is surely
the text we're presented with contains several references to varieties of apple.
Many years ago, Macintosh does not have a place in the technology field.
Nokia was the beacon, the headlight of the kingdom of technology.
Yet, there is a hidden force,
Just a reference to Sir Isaac Newton?
in the far East,
There are lots of Japanese apple varieties, some named after places in Japan. The most obvious candidate seems to fit better elsewhere (see below). There don't appear to be varieties called Orient or Sunrise, though there is a Sunset. Not sure exactly what we're after here.
triggered by the extreme jealousy.
The owner of what is now known as Nikoli
The puzzle publisher Nikoli is named after a successful racehorse, hence a Champion. (The owner of the publisher is Maki Kaji, and there doesn't seem to be an apple variety of that name; the owner of the racehorse, an Anglo-Irish nobleman, has a number of names and titles -- Guinness, Iveagh, Elveden -- but none seems to match an apple variety.)
was standing on top of the mountain,
The mountain may be Fuji.
trying to make his depression fade away
Not sure what's up here. There are various kinds of apple with "Delight" in the name, but that's a bit loose.
with the light wind that caresses his cheeks.
While people are struggling for power
Not sure what's up here. There are Empire and Liberty apples, either of which might be kinda appropriate here.
and the leading status in technology,
Not sure what's up here. Just another reference to Apple-the-company?
in the capital of Italy,
people, despite having almost no access to technology,
Presumably this is pointing at something but I haven't found it.
are relaxingly dancing
Perhaps Jazz. There's a Flamenco too but I don't think that's very relaxing. (Also Fiesta, Gala.)
in the Stone Hall.
This must be referring to something too, but again I've failed to find it. There are a number of varieties named for places that probably have stone halls (e.g., Blenheim Orange) but I'm not sure any of them have stone halls that are specifically called "the Stone Hall".
