During the interview, Jacobs told Rose (via VentureBeat) that before smartphones existed, he pitched an idea to Apple that had in it the basic underpinnings of the now prolific mobile technology: a Newton PDA with embedded Qualcomm radio for cellular communication. The idea was rebuffed and Jacobs took his plan to now-defunct PDA maker Palm, which ultimately partnered with the company to create the Qualcomm pdQ.
While largely a forgotten device in a sea of mobile electronics from the 1990s, the pdQ is arguably one of the first smartphones to hit the consumer market. The application driven OS and mobile capabilities were a precursor to modern products like Apple's iPhone and offerings from Android handset makers.
At the time, Apple chose to go another way with the Newton, offering customers expansion slots for customizable connectivity options instead of building in a dedicated radio, which would have added heft to the already large device. Even Qualcomm's offering, seen as a kind of hybridization of the PDA and cell phone, was gigantic compared to today's standards.
From a CNN feature from 1999 regarding the pdQ:
The unit itself is fairly large for a cell phone. At 6.2 inches tall, 2.6 inches wide and 1.4 inches thick, it is too large to fit into a shirt pocket comfortably. It can slip into the pants pocket of a pair of khakis, although a belt holster would be more appropriate. Weightwise, it comes in at around 9.8 ounces, but isnt uncomfortable to hold for long periods of time while talking.
Compare those specs to the iPhone 5's svelte chassis standing 4.87 inches tall, 2.31 inches wide and 0.3 inches thick with a weight of 3.95 ounces, not to mention the bevy of cellular and communications radios, 4-inch Retina display, speedy A6 processor and advanced microchips Apple was able to cram into the small aluminum housing.
Still, Jacobs' story offers a look at what might have been given Apple's strong performance in the smartphone market that many believe was brought into the mainstream with the first iPhone in 2005.
Jacobs will be kicking off the Consumer Electronics Show in Las Vegas next week with a keynote speech, replacing the usual speaker Microsoft's Steve Ballmer.
