While there was no actual update to the iMac line, Devir Kahan made a great point:
This really seems like the first real professional-grade portable machine. This is the sort of thing that really makes me consider going laptop only (with a Cinema display for at home).
I’ll take this one step farther and question why I would ever consider going desktop again now that this much power meets this much portability (other than the obvious answer of price).
Things have been heading this direction for a while and I don’t think we’ve seen the end of the iMac just yet. But once the cost of both the MacBook Pro Retina and the Cinema display begin to drop, I can’t see why anyone would consider an iMac.
