It looks like the Core i5 750 systems had their prices adjusted against the older XPS 435 MT that was dropped and the XPS 9000 takes over.Does no one in your company have a desktop or workstation? Is everyone happy using a laptop for whatever task they're assigned?
But you're right, if Apple wants the Imac to compete with laptops, it's well positioned.
On the other hand, Dell is selling 3 GiB Core i5 quads for $699.
On the business side the Vostro 430 has appeared as well. Under P55 it's amazing how much power you can fit into a Micro ATX system. At 95W for the processor and dropping the northbridge, they're much cooler systems.
