We just got a poundhost server at work and have had no problems so far. The 100Mbit connection is ever so slightly faster than the 256kb one the website is currently sitting on.
A quick google for Rackspace will show you that they're no better than most other half decent hosting companies in terms of outages. But they do have great marketing.
Any server can go down. It's about the communication and customer service you get when, not if, it happenends.
