Cyber Nostalgia
I read a great post couple months ago about Kozmo.com, titled, "Why The Web Still Weeps for Kozmo.com".
Apparently you can still buy old Kozmo paraphernalia on eBay, Craigslist, and elsewhere.
I have my own Kozmo memorbilia and this one – Lady Liberty with the Kozmo bag slung over her shoulder is my favorite.
