Seriously. We are looking at hosting right now and are considering Rackspace and Joyent. In fact, I am one of the lifetime hosting people screwed over by this move, but this makes it an easy call. No way we are trusting Joyent with anything.
Rackspace are amazing. The only gripe I have (which isn't minor, I might add) is that you can only buy machines in tiers. If you want a machine with high network throughput (say, like a proxy), you need to purchase lots of cpu, ram and disk space that you have no need for.
In the same vein, I can buy a Honda Civic for $10K, but a car with custom specs isn't $12K, it's $some_orders_of_magnitude_more, even if it's equivalent to a Civic in almost every way.
