Agree. But we should then be saying "omg 1.5ghz full system in that form factor!" Not that such high spec system can run a sub average set of software intended for old 486
Btw, the pizza boxes were considered incredible small back in early 90s :)
The sgi Indy even had a "portable" version with attached lcd screen.
The novelty is the size of these devices. I also run Word and Excel on a 386 at 40 Mhz but it was a full tower not a credit card sized box.
