Rumour of touchscreen Mac mini notebook surfaced again. It would be 7 or 9" display like large touch iPod. It would be released during Fall of 2009, if rumour is correct.

I am expecting such a touchscreen tablet PC from Apple this January Mac World expo. But rumour is disappointing that it is only for Fall 2009.:D
