Dell just announced a 32" 2160p IGZO Ultrasharp coming in Q4:
Currently Dell's most expensive display is a 30" Ultrasharp at $1250. It looks like they've finally ditched VGA and DVI - the ports on the bottom appear to be displayport, mini-displayport (or Thunderbolt perhaps) and HDMI.
Maybe Apple will have a high resolution Thunderbolt display ready for the Mac Pro launch. It'll look better than the Dell one too as it'll have the laminated anti-glare front so deeper black levels and can be as slim as the iMac at the sides with USB 3 ports. The internal speakers might not sound very good with such a thin chassis but there's no harm in having them.
This would be the first time Apple has moved away from IPS for a very long time too:
A 32" display makes little sense to me for most uses. The typical offering went from 30" 16:10 to a 27" 16:9, overall significantly smaller. 32" is just a huge amount of area to scan visually, and no OS on the market today has an effective way of partitioning screens in any way. It's basically the same thing, but spread further apart. You end up having to use a lot of mouse acceleration, which can be incredibly annoying. The touch display sounds cool, but it seems like an odd implementation. A touch display would need to be angled for reasonable ergonomics.
I dunno, Intel Iris 5200 and Nvidia GeForce 650M are very closely matched with the 650M just pipping the 5200 in terms of ultimate performance. While Iris would offer huge power savings it puts Apple in a difficult position as although they don't want a new product's graphics to be slower even marginally than the previous generation (especially on an expensive pro product with a retina display) in order to provide discrete graphics that is meaningfully more powerful than Iris they will have to go to the highest end of mobile graphics which would end up dramatically increasing costs and power consumption........ The truth we know right now is that the 15" MBP retina prototype that popped up on Geekbench didn't have a discrete graphics chip when tested
It wouldn't be a 650m either way. It would still be a kepler gpu if NVidia or whatever AMD has out. The iris pro still consumes more power at a higher chip cost when compared to other cpus. They could use it anyway. To say that they would have to up the discrete gpu is completely disingenuous. The 7xx gpus are clocked a bit higher in general, and it would be in the same class. Only a couple oems ever go past the mid to upper-mid range gpus in a 15" notebook.
