Will the BlackBerry Passport prove to be BlackBerry’s big comeback device? That’s still in question but the device has definitely generated some solid early interest — per Counterpoint Research analyst Neil Shah, BlackBerry CEO John Chen said on Friday that the company has received 200,000 Passport preorders over the last two days. While those obviously aren’t Apple or Samsung-type numbers, BlackBerry doesn’t need them to be since the Passport was designed to be much more of a niche device aimed squarely at corporate power users.

Elsewhere, we see that BlackBerry is also boasting that the Passport has become “the number one selling unlocked phone on Amazon.com within hours of launch, which our partner told us is unprecedented.”

Of course, rising to the top of the Amazon.com phone sales chart is no guarantee of long-term success, as it might only be due to pent-up demand from diehard fans who are scrambling to get the device. Recall, for example, that Amazon’s own Fire Phone quickly rocketed to the top of the Amazon sales chart and it’s widely considered the most spectacular flop of 2014.

Officially unveiled earlier this week, the Passport is most notable for featuring a 4.5-inch square display with a resolution of 1,440 x 1,440 pixels and also features a Qualcomm Snapdragon 800 2.2GHz quad-core processor, 3GB of RAM and a massive 3450mAH battery
