Thanks for the tip, unfortunately, I ride on a recumbent so that won't do
Anyway, here's Dahon's answer :
"As Dahon is a relative newcomer to the electronics field, we have only introduced the Biologic Bike Mount to fit the iPhone. In the future we will plan to branch out to fit other popular brands of cellular telephones. I will forward your message to the Dahon Product Development team so that a vote for a Bike mount for HTC Desire is entered."
So feel free to send the an email to enter more votes
