With word processing, if you were currently using a typewriter, and correcting tape/fluid, and editing, and re-typing pages (and, hey, change your mind about the name of the protagonist in your novel? one command)... that seems a very easy sell.
Spreadsheets also seemed an easy sell from the start (e.g., accurate instant calculations of, say, current paper ledgers, without a calculator). Even before people understood all the new things they'd be doing with spreadsheets that weren't practical or convenient before.
("Education", "balancing your checkbook", "organizing your recipes", and other early pitches for non-business ordinary people home computers... not so much. Though a lot of ordinary people tried programming.)
One distinction with the Web might've been that (at least initially) although it might've made ordinary people want to use a computer, they didn't immediately see what it was good for. Initially, you could wander around Yahoo, and click to some Web museum experiment, and that was a novelty and a nice demo you could extrapolate, especially if you were an ordinary person into science fiction or futurism. But mostly you knew a bunch of companies were suddenly throwing money at it, and that those companies also didn't seem to know what it was good for. But lots of people wanted to be there.
Had to get my mom to drive me to a service bureau near the university that would laser print pages - $1 a page. Our highschool paper looked better than most of the indy papers in town. It was revolutionary tech that we now just take for granted.
I remember getting excited over the first bubblejet printers - finally affordable laser like quality!
I had a childhood very tiny shrinkwrap software business then, and my packaging was based on paper inserts in clamshell packaging (lower startup costs than actual shrinkwrap machine and supplies).
Places were offering color laser prints for $1 per page. That was a little too painful, and my tools for mastering were limited (monochrome paint programs that wouldn't even display square pixels, and some bits manually taped up). I ended up using a normal print shop for offset printing, using one standard (unmixed) color, and I think the guy gave the little kid a discount, and also fixed the tape-up. First product had a standard blue on white paper stock (with a couple colored circle stickers like for garage sales, printed with things like version number on my 9-pin printer), and the second was standard red on canary stock.
We actually did a youth group newsletter a similar way, except with more tape-up (every little big was printed separately), and just 5-cent photocopying.

Go watch the original iPhone launch keynote with Steve Jobs. Before the iPhone "mobile internet" was a completely separate version of the 'net - if a site even bothered to create a WAP version of themselves to render on phones. Before the iPhone the only thing consistently useful on a mobile "smart phone" was email. Having a real web browser that rendered real web pages was a watershed moment!
