BlackBerry Tour facing 50% return rate? Trackball again…

Rumours are circulating that the BlackBerry Tour is facing return rate of 50% which is huge in any market! The culprit is of course the trackball which has been a continuing problem on many BlackBerry smartphones in the past. I lost my first Curve 8900 because of the trackball and now my new one started playing up this morning (won’t scroll up). It is an issue which plays on my mind because I am just waiting for it to go again, and so the new optical navigator will most likely appear on all new BlackBerry devices.
