iSlate will not be a tablet
August 28, 2009 Apple filed for patents on a new type of keyboard. This keyboard is a multi-touch keyboard with tactile feedback for users.
"The invention is credited to Wayne Carl Westerman of San Francisco, Calif. The described invention would include drive electronics that stimulate the multi-touch sensor and sensing circuits for reading the sensor in a single integrated package." -Apple Insider
This patent suggests that our predictions are correct. The supposed "iSlate" will not be a tablet but a clam shell notebook computer with multiple touch interfaces. One of these interfaces will include a dynamic tactile keyboard.
