Just got a Gamevice and am very disappointed with it. Several of the buttons are stiff and very unresponsive, to the point where I can press several times without it registering. I've seen this mentioned in reviews of Gamevice (though I never thought it would actually be this bad), so I don't think I just got a bad unit... I'm thinking of returning it now, but I'm wondering if anyone has found that the buttons just need to be 'broken in' before they start working properly? I'm afraid to start carrying it around and giving it heavy use to try and find out, in case it gets scratched or something and Apple won't take it back.
