After reading all the reviews I'm planning to get the new design Nutshell leather case for my 650. Wearing it horizontal sounds appealing so I'm getting the belt loop rather then the clip.
Does anyone have any experience with wearing a treo 650 with the nutshell case horizontal? Do I HAVE to get the top tab with velcro if I plan on wearing it horizontal to ensure that the Treo doesnt fly out when wearing it horizontal? I'd rather wear it horizontal without the velcro tab on top, provided there is enough grip/friction to hold the treo without the flap.

Thanks !
