Want to get tech fans fighting? Ask them to pick the 10 products that most shaped the industry. It’s an experiment we attempted earlier in the week, to fairly disastrous results. Since our very opinionated editors and analysts couldn’t whittle the list down to anywhere close to that number, we’ve decided instead to leave the voting up to you, the PCMag reader.

We’ve split our coverage up into five categories—desktops and laptops, software, cell phones, consumer electronics, and gaming. Each round, we’re offering up five products that we believe have had a profound impact on the industry as we know it. When we say “profound impact,” we don’t necessarily mean that they were the first (though in many cases they were). In some cases, the product is the first in its class to really capture the imagination of the development community or the public at large. We’ve got a pretty broad timeline here, as well. In fact, the first entrant in this first round was released in 1977.

Of course, “the most influential” is a fairly subjective title, so we expect that there will be a fair amount of debate, both in terms of our finalists and the winners. So please, if you feel that we’ve made any glaring errors on our list—or would just like to convince fellow readers to vote for your favorite candidate—please let us know in the comments.

Here we go with round one: Desktops and Laptops. Each slide features an image of the product and an explanation about why it was so important and influential. The poll is on the final page.
