Some lists pick themselves. Then there’s the list of the most influential technology. After a good amount of debate around the PCMag offices, we’ve opted to let you, the reader, help us choose the winners. 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 four 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.

Perhaps no other round better demonstrates how far we come in a short amount of time than the cell phone category. The first entry on this list, Motorola’s StarTAC, dates back to 1996—a mere decade and a half ago. The StarTAC’s clamshell design was groundbreaking at the time—a model of gadget portability.

Fast forward to the iPhone in 2007—the most recent entry on the list—and it’s difficult to fathom that we’re talking about the same space. Apple’s handset is, for all intents and purposes, a pocket computer, and in many ways, the device’s functionality as a phone is really secondary to its ability to browse the Web and perform countless tasks via its ever-expanding App Store.

Here’s round three: Cell Phones. 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.
