As someone who sells VPSs for a living, well, I'd want a pretty significant discount to take a VPS over a dedicated server of the same specs. The big problem with VPSs is I/O. If you have a 1TB disk and you split it so that two servers are using it, each server, sure, gets 500gb, but each server gets /way less/ than 1/2 the I/O performance. When you have more than one server hitting the same disk, all your sequential transfers become random transfers, and random transfers, especially on the SATA that nearly all VPS providers use, suck.
