Well... *blushes*... I thought you were saying that DRM wasn't a lock-in. Teaches me to jump into a 17-page-thread without re-reading it again for clarity. I see now that you're just saying that DRM lock-in isn't "an issue"?
If we agree than DRM is a lock, then the issue of whether or not lock-in is "an issue" becomes so individualized and subjective as to basically boil down to "well, it is/isn't for ME."
