The reason I didn't adopt Inbox (for Android) initially was that it only worked for GMail whereas the regular GMail client also worked with 3rd party mail accounts. I was also extremely hesitant because of Google's history of canning experimental apps and Inbox simply isn't integral enough to be safe from the routine culling (unlike e.g. Chrome or Maps). I was an early adopter for Wave (which ended up going nowhere because nobody I knew wanted to give it a try and I didn't have enough invites to hand them out without knowing people would use them). I tried to get on Orkut but never got an invite (until it had already basically become the "Facebook of South America"). I strongly believed in Google+ as a potential Facebook killer and used it early on. I was also an avid user of Reader in the Web 2.0 days. At this point, I no longer trust new Google products. Google seems to really want me to use Duo, for example, but nobody I know is eager to use it and I won't talk my friends into using it if it's not clear that it's here to stay. I'm not committing to any Google product if I don't have reason to believe they won't pull the rug whenever they please.
