laptop and notebook

[Glenn Bach <gbach@xxxxxxxxx>]

Hello,

I'm looking for scholarship/references to the use of the terms "laptop" 
and "notebook" for portable computers, specifically with regard to the 
anthropomorphic aspect of the word "lap," (laptop as a take-off of the 
term "desk-top"?) and the analog quality of "notebook" (a book of blank 
pages for notes).

As a tangent, a friend has suggested Heidegger's discussion of typing 
with two hands being less "human" than handwriting in cursive with one 
hand.  Also, Derrida's discussion of archive.

Any suggestions?

Thanks,

G.
