I just renewed my LR and PS CC subscription, I find it a small price to pay for the continuing use of someone else's intellectual property. I am happily working with the .4 version of LR CC, at some point I will click on the upgrade button, but so far I have not felt a need to do so. I also have the earlier standalone version as well as the whole CS6 suite – belt and suspenders syndrome!
I think that LR, and PS, have now pretty much reached the limits of what is needed by any photographer. I am hard-pressed to find desired improvements, I can think of a few, but not many.
The most important part of LR is the print module. Whether or not it is the best printing module available or not is not particularly relevant, what is important is that it alone allows for the preservation of my images. At some point,sooner that we want, the technology we now use will become obsolete, our files stored on hard drives, flash drives, the 'cloud', will become unreadable since the new machines will not be able to read those files. I have quite a collection of backups on 5.25" floppies, Zip Drives, and Syquest Easy drives. None of those are readable by my new iMac, that is a lesson from fairly recent history. I hope to be able to continue to use LR for many more years, printing.
And, if any LR development team members read this forum: thank you.
