I have recently been thinking about moving to digitalocean, because they look like excellent value. I haven't made the move yet because of inertia, and Linode's customer service which is just mind-blowingly good. I suspect that in a couple of days I won't be able to spot a single patch of greener grass on the other side of the proverbial fence.
I really wish DigitalOcean provided more then one core on their plans with < 2gb of memory. Despite that, I am probably going to move to the 512mb plan in the next year or so (once I get around to it). The backup feature is enough incentive alone.
