I find that perspective completely disingenuous.

First of all we should recognize these things as mobile computers. At least the iPhone keynote made the distinction that it encapsulated three distinct devices and ran OS X, but then the complete discourse got hung up at that useless phone categorization.

Second, the form factor derives from human anatomy. If you want to innovate human anatomy, take it up with the laws of biology and physics. Phone design made enough mistakes by messing with the device size.

Third, only recently, phone design completely overhauled the enclosure construction, advanced glass types, aluminium and steel alloys, fewer mechanical elements, even Titanium, notoriously difficult to machine, appears to enter the mix more prominently soon.

Then recent devices completely overhauled wireless connectivity, UWB, Bluetooth and Wi-Fi revisions. 64bit chips, secure enclave, dedicated machine units, advanced biometrics, laser scanners, advanced camera optics, advanced speakers, wide color, HFR, color temperature adapting screens.

PCs have had no comparable innovations in decades, yet no one seems to lament this for sake of self congratulatory rambling.

If you avoid to look past the trivial surface, you will find anything dull pretty fast.
