I was pretty shocked how bad the screen is, scored something like #26 of 28 phones in brightness, similarly poor with saturation accuracy. Arstechnia seems to think the slow I/O is the worst offender for the general laggyness. Read bandwidth was 73% of the nexus 5, 37% of a note 4, and 30% of the Moto X 2014 (well regarded for it's responsiveness).
Pretty disappointing. Too bad google didn't pick something like the droid turbo/Moto Maxx for the next nexus device.
> The Nexus 6 shows significant regression in color accuracy from the Nexus 5, and the maximum brightness is much lower. It should also be noted that despite its higher resolution, its larger size means that compared to the Nexus 5 the pixel density only increases 12% from 441 PPI to 493 PPI. The use of a PenTile RGBG subpixel layout also means that there is actually an overall decrease in subpixel density.
> Overall, the Nexus 6 display is quite poor relative to the displays on other smartphones like the Galaxy Note 4, iPhone 6, and HTC One (M7). It's also a definite regression from the display on the Nexus 5, which is concerning given the fact that the Nexus 6 is $300 more expensive. It has been speculated that Motorola is unable to source the latest generation of panels from Samsung Display, which would explain why many of the panel characteristics are similar to previous generation AMOLED panels in the Note 3 and Galaxy S4. Although the efficiency of AMOLED displays when displaying black helps to reduce power usage with features like Ambient Display which wakes up the phone when notifications arrive or it is picked up, I don't believe it's worth the trade-off if it involves such heavy sacrifices in color accuracy and brightness.

The thing that's got me irritated is the sub-par camera _again_. I'm really frustrated with the camera on my N5, and I'm now worried that the only place I can go is an iphone 6+. Do not want. :(
LG G3 or Xperia Z3. Probably the best photographic phones on the market by a long margin ( assuming you are outside China and can't lay your hands on a Vivo Xshot ).
Edit: the Note 4 camera is said to be pretty decent but not quite in the same class, though the screen has excellent accuracy. I have no experience with Nokia-Microsoft phones.
Technically, better ( honest-to-the-scene ) cameras and lenses.
But Apple does a lot of magic in software to make their images 'pop'.
I think it's probably comparable to, say, Sigma versus Zeiss SLR lenses. Sigma make some astonishingly good wide-angle SLR lenses but Zeiss give a certain appealing 'look' even if they're actually less competent in some measurements.
 yes, they of the mega-zoom infamy. But their new Art series of lenses is amazing.
Highlights: the screen and external speaker. The newest Moto X is a larger than the one I have. I think it's in between the Nexus 5 and 6, in size.
The only issue I have with the new Moto X: can't unlock the bootloader.
A year ago, we had a 5" smartphone (Nexus 5) for 399€ and a 7" tablet (Nexus 7) for 299€.
Now, we have a 6" smartphone (Nexus 6) for 699€. Is it reasonably priced?
The Nexus 6 (184g, 31g/inch) is heavier than the Nexus 5 (130g, 26g/inch), compared to its screen size.
While the battery capacity of the Nexus 6 (3220 mAh) is significantly larger then the Nexus 5 (2300 mAh), people reported the battery life of the Nexus 6 to be shorter.
I can't find any technical improvement that could explain a 1.75x price increase.
I was hoping for something good.
That one article I'm not reading then.
These devices still don't have more than 4 GB of memory, let alone single applications pushing that limit, and it's not x86; the biggest win in moving to amd64 was the increased number of registers.
Which is not to say that there aren't others, but I don't think it's a clear-cut as for x86.
All of which is to say that I don't know. How would it help? Please explain, as I'm not that familiar with ARM hardware.
Plus there's a raft of Chinese-market 64-bit phones already, waiting for Android 5.0.
I mean, the Oppo R5 is the World's thinnest phone and it has an eight-core 64-bit Snapdragon chipset! We are so far behind in the 'West'...
