Thanks for posting these. I'm currently using the lowest tier of Slicehost, but it sounds like I can easily halve my costs with this new service without a decrease in RAM or storage. I hope Rackspace will make it easy to move from Slicehost to this new cloud service (both of which they own).
The only thing that sounds rather odd is that they're charging more for outgoing traffic than incoming traffic - most websites send much more data than they receive, so I would think that Rackspace would configure their network and their prices accordingly. Granted, this cloud compute service doesn't have to be used for websites, but Rackspace has traditionally been a web hosting company.
A large hosting company cannot configure their network asymmetrically because AFAIK the backbones only sell symmetric connections. So Rackspace has symmetric pipes that are mostly empty on the inbound side and they charge less to encourage usage.
