While you may get a small portion of dedicated memory, there is generally no dedicated CPU allocation, disk i/o, network i/o, etc. In addition, most VPS providers only offer smaller amounts of resources, 256MB-1GB of memory and no options above this. And the largest problem by far is VPS platforms are typically oversold, so one physical host machine is running far too many customers and this turns into a resource allocation nightmare causing server crashes or poor performance (or both). There is no isolation from other customers.
