The risk of 'Neither-Nor'

The opportunity iPad's latched on to, is the vacant product space between a phone and a laptop. Yet the risk it runs is that very same space meaning nothing, because it could turn out be neither a phone nor a laptop in the consumer's eyes.

The initial sales of iPad have been disappointing. But these are early days as other Apple products too took off after a slow start.

Its worth waiting to see which way the iPad product curve goes.
