I haven't checked for a while, but when I compared Slicehost and Linode pricing, they were about the same. I stayed on Slicehost for that reason. Slicehost has been great to me, and I like their IRC channel. I see no reason to switch. I guess I'll go compare again soon and if there's a big difference I'll be obliged to switch (very poor), but I haven't had any trouble with Slicehost.
