How popular is the Treo?

I was at a conference today, held at a top class hotel. I had a lot of calls to make (or is it that I keep checking my emails?). Near the end of the day I am in dangerous red territories regarding battery life. I went to the concierge to see if they have a charger. She give me her box of chargers left behind by other hotel guests. It has chargers for new and old style Sony Ericcson phones, Motorola phones, mini USB, a few others that I do not recognized, but nothing for a Treo. My first thought -- the Treo is not that popular?

My second thought -- Treo owners are better organized and not likely to forget their charger at a hotel?
