Ahhh some dev is going to see this as a challenge.
My have times changed.... an article like this 2-3 years ago would have resulted in mass emails, tweets, and complaints from the community.
Now, people are like...ehhh Im over my root phase anyway.
I am in that camp. I have not rooted in a long time, and I currently own a nexus 6. There just isn't a huge need for it these days, as the stock ROMs have really gotten a lot better.
I have found that the only real reason that I could use root for is customization, but with a gazillion launchers out there, you can pretty much customize whatever you want with those, for free, without risk of messing up your phone or not getting an OTA, etc...
I have yet to find a custom ROM for this phone that works better than the stock one, they all tend to have at least one issue, or some app of mine that won't run on it...
It reminds me of the PC overclocking era... I started overlocking my PC back on a Cyrix 686 PR133... That's how far back I was doing it, I just dated myself there... haha
It was great to get near the performance of the $900 CPU out of the $300 CPU... But after several years, the law of diminishing returns kicked in and mid range and affordable CPU's were so fast, that risking drying your rig with exotic water cooling systems just to gain another 4% score in a synthetic benchmark, just wasn't worth it any more.
I feel like phones are hitting that point now, from a software perspective...
For those doing it, more power to them, but I think that like the PC, a lot of us that have been doing it a long time, come to realize that as time goes on, you spend a lot of time tweaking and fiddling, and in the end the gains just are not that much...
