When I worked for one of the largest banks in the world, they toyed with ipads, they tried to put forward innovative business reasons, but at the end of the day, it was the rich boys at the top who just wanted something they didn't know anything about for free, because it was fashion.

I work for another global company (considerbly smaller) and they are now doing similar things. Ironically we missed out on a annual company target by less than ??1million, because we wasted so much on ipads, iphones, new high spec laptops for people that browse the web and write the odd letter.

Quad core processors are coming into phones, this is enough for most people to do their jobs. A cradle for the monitor, input and network and then stick the phone in job's done. but we just arn't there yet because no one has shown it works on a large scale.
