The "issues" with the hardware are these:
Brightness:
218 against 287 to 588 nits for the rest. It's the least bright screen. The Nokia N9 was the one with 287 nits, so it's 24% less bright.
Contrast: 425:1. I would expect at least 700 or 800 here. The best ones having more than 1000:1 contrast.
Color-accuracy: 6 (lower is better) against 4.1 to 2.1 for other phones.

Battery: non-issue, solved with the "NFC-hack", as is mentioned in the review. Startup-time camera: 4.68 seconds against 3.6 to 1.51.
That's 1 second behind the second last and 3 seconds behind the first of the bunch.

I would have to rely on your experiences with the device. I'm sensitive for screen quality. Resolution is not that important to me, but contrast, brightness and color-accuracy are. I'd like to have a bit of a color-real screen, so it would match my calibrated displays at home.

I'm not sure. The numbers don't lie and the website tweakers.net is a very respected site in the netherlands. But I don't see the numbers relate to user-experiences (before and after the review).

When I have the chance, I will see if I could get my hands onto the device and judge myself. It doesn't have to be top-notch, but I expect some quality. If Sailfish will become available as a download, I could get it on my Samsung Galaxy S3. It could be possible it has better hardware compared to the Jolla. I already have the SGS3, the Jolla would cost me €400 (selling my SGS3 for €250 it would cost €250). What would you do in my situation?
