There is no cell in my body saying "yes, let's get that".
To me, google glasses seems like an effort of actively decreasing interference with people physically present around you. I like people. I won't get these glasses.
Also, as this video aptly illustrates, no word is less cool than the word "cool".
ps. In my original post, I wrote "weirdly autistic tool". Robin made some very wise comments on my choice of words. See comments. Now am actually more interested in the glasses than before!
