The MBP comes with TN, not PVA. PVA is actually a fairly good technology. S-PVA has the darkest blacks of all panels, but is really really slow. You can see the ghosting when the camera pans in a movie.
Ah. From what I've read now, only some models of the Lenovo X200t ever shipped with PVA in a laptop (some were IPS, some were PVA). I guess different qualities of TN make a difference.
It all makes the IPS panels in the iPads even more impressive. From what I've read the IPS panel yield goes down with DPI, too, so the panel in the iPad (Early 2012) is amazing.
