I've got a con for the Rackspace list, that in some was conflicts with one of it's pros. Pricing is simple because of the small choices for instance performance. I would love to have more choice in instance performance beyond memory based tiers. I'd kill for a c1.medium analogy on Rackspace. With that being said, I'm a loyal Rackspace customer and love their cloud offering.
