Writing in Business Insider, Steve Kovach predicts that the Moto X will be a flop, just like other high end phones that have failed to penetrate the market.
He sites the HTC One, Blackberry Z-10, and Nokia's Lumia line as excellent phones that didn't sell. His rational is that, currently, the high end phone market is basically dominated by Samsung and Apple. While he argues the Moto X is a top tier device with a unique feature set, there isn't anything that will make users switch.
Following my briefings with Motorola execs and my time with the device today, I see nothing here that will cause people to make the switch. That doesn't make the Moto X a bad device. It's not. But it does make it the latest example of a saturated smartphone market where too many voices are trying to shout above the noise of Samsung and Apple.
That being said, one could make the case that the HTC One, while not quite up to the mark of the Galaxy S4, still had a respectable sell-through.
Surprisingly, there hasn't been much comparison between the Moto X and the Nexus 4. It seems clear by now that Google isn't replacing the Nexus brand; the Moto X is still Motorola. But the approach might be similar - to create devices that are not necessarily designed to sell well (right away). The Nexus 4 sold relatively well (for a developer phone), but its predecessors didn't. Google spent years strengthening the reputation of "Nexus" brand. The Nexus 7 is very successful for this reason.
The device is set to be released in a "few weeks" according to Guy Kawasaki, who interviewed on TWiT today.
