I have been an active BB user for a decade, and was very reluctant to move from the side trackwheel to the center trackball format, but that is the only option now. So I just got the Tour, which I generally like.
But there is a glaring oversight, which (once addressed with a software upgrade/app) would make the Tour much more approachable for former track-wheel users like me: It is very simple:
Allow users to desitnate, as a Side Convenience Button, one convenience key to be another "ENTER" key, and also a side convenience key to be used as another MENU key.
As it is, the only way to ENTER is to click the trackball or to push the very small return button. The large side convenience keys would be much more suitable for this much used function (as well as the menu function)
To some, this may seem redundant, buf for those of us used to using the sides of the blackberry to perform essential functions, this would go a long way to easing the transition!!!
