The m9r is out for a while now. While it took some time to get the m9 to where it is today (thus the blog name “the whole 9 yards”), the introduction of the snom m9r was so smooth that it was practically unnoticed.
The m9r was modified only in areas that have very low risk of bringing in instability. More memory never hurts in the computer industry, and on the handset side there were improvements with the handset plastic and acoustic. Also the antenna design was improved, giving the m9 a longer range than the m9 had before.
I believe that is okay. Stability is very important for the users of DECT phones; fancy features are expected on smart phones but for a DECT device, customers essentially want no surprises. The m9r is essentially like a facelift in the car industry, when they change the bumpers and throw in a few more extras.
The big question will be if we should come out with m9r firmware releases that take advantage of the increased memory. For example, I saw the comments on ZRTP: We did not include ZRTP on the regular builds because it takes up too much memory for stable operations in the m9. But we could include that in the m9r builds where memory is not such a problem. For now, we do this only for special builds and prefer to keep both variants with the same software. It does not only make our life easier, it also important for the m9 users that they continue to have access to the latest firmware.
