I'm curious about this also, since my girlfriend is out shopping to get me one right now.
Any comparisons to the Belkin armband? The reviews on the apple store seem poor, but I can't find any for these to compare with. I like the idea of the key pouch on some, but I want something comfortable that I would actually use.
The Sporteer doesn't look very secure, and that's probably my main concern.
The Sportsuit has this convertible feature, but is that necessary? I'm planning on using it just for running, and the benefit of a removable sleeve would lead me to believe it is less secure.
Any insight or comparison from people who have used them would be very much appreciated.
