I'm working on it, but yeah, if you need a easy control panel to quickly re-image your system or things like that, I don't yet have those things, and yeah, for some people, getting those things is unquestionably worth the price difference between my competitors and I.
But for people who do have more UNIX/Linux experience, I think my system has some advantages that I will be careful to keep as I try to make easier interfaces. I give you a rescue disk that lets you boot your vps even if you break your boot config. I give you a ssh public-key based out of band console and rebooter. I let you run whatever kernel you want (I have a few customers running NetBSD, and I have some experimental OpenSolaris domains)
And I just couldn't care less. That's like one night's worth of sales. I've (hopefully) got better things to do with my time than spending it preparing for a migration and inevitable breakage in the interests of saving myself an hour's salary a month.
