Definitely, just a few things to know going in:
1. This is the best overall phone Nokia ever made before being bought out IMO. It may not have the best camera they've ever made or the biggest screen, but all things considered I believe it is the best all around phone.
2. There are some cosmetic issues you do have a high chance of running into, but they are minor and people generally don't notice them unless pointed out. Those include:
* One or more corners of the screen not being 100% flush with the aluminum bezel.
* Screen colors not exactly uniform across the screen
Generally, neither of these issues cause a functionality issues and some never even notice them. Some of the devices do not have them either - I have two 930s, one has both problems and one only has the second problem mentioned above. But neither one affects the phone any way and unless someone knew of these problems ahead of time they likely would not even know they are problems. The other issues you mentioned are much less common.
So, I believe what you are reading about defects/etc is valid, but it is something most would not notice/care about unless they analyzed their device because they are relatively minor. I believe all smartphones have their issues, for instance look at the best selling iPhone 6 Plus - thing literally bends in half with minimal pressure - now THAT is a major issue.
In summary, buy the phone if you want the best overall Nokia ever made. No guarantee we will see another phone this good with Windows anytime soon.
