The reader goes on to say that his informant was fresh from a meeting when s/he shared this little tidbit. Perhaps using her iPhone. In the hallway.
The takeaway is obvious without this post: The tablet will behave in a way that we aren't expecting. For some, the iPhone's UI took some learning, as most consumers hadn't seen a touchscreen device before, let alone a touch-based phone. That doesn't mean it will be difficult to use, just different.
Rumors are rumors but one thing is certain: they're only going to get worse between now and the tablet's release.
