they are not complete, but to the extend that these projects are successful (and they are doing much better than the openmoko before it), eventually a fully open hardware phone will emerge.
basically my confidence is based on these trends. it is likely that an open hardware phone will always be a niche device, but for the past two decades attempts have been made to build such a phone, and i do not believe that these attempts will just stop.
on the contrary, as hardware production gets cheaper and cheaper, as the performance of these phones improves and will eventually reach a peak like it has with laptop and desktop devices, it will be easier and easier to actually produce a fully open hardware based phone. at that point the only thing getting in the way would be lobbying and aggressive acquisition by competitors that do not want to see an open phone.
a good example on the laptop side are framework laptops. similar attempts were made before but only now i find these models actually competitive in terms of features and price. (i am only waiting for them to offer a keyboard with a trackpoint like thinkpads, for them to be an alternative i can use)
open hardware devices will probably always be behind the most cutting edge features by a few years, but these features matter less and less, and to the extent that a 5 year old device is still perfectly usable today, so will an open hardware device with specs that are a few years behind the latest and greatest
