My actual policy itself will probably remain the same: I have two Windows 10 devices: a big DIY gaming PC which is not on the insider program, nor will it probably ever be, and a cheapie little off-brand Windows 2-in-1 that is on the fast ring and will remain that way until the day I retire it.
However, what has been changing is that as that 2-in-1 (specificaly, a Nextbook Flexx 11) has been aging very ungracefully, it has been creating its own counter-incentive to using it, causing the actual level of my "on the ground" involvement in the insider program to have sort of gone off a cliff. So, when I say "until I retire it", it's really not that far from being retired already.
In fact, as a vivid illustration of this: when I fired it up the other day, I was surprised and disappointed in myself to have found that it had been so long since it was used that it was still on one of the final builds of the rs3 branch.
This lack of in-depth involvement in the program has led to cooling enthusiasm about it in general for me, though I am still on-board with it at the ideological level, and remain interested enough that I still at least skim every article that WC puts out about new builds - and pay extra special attention during the more exciting phases of the cycles when they're bringing in all the fun new features.
I dunno. Maybe I'll invest in a slightly less cheapie 2-in-1 (or at least in another new super-cheapie, like the Flexx that hasn't aged poorly...yet) and get back to taking the insider program more seriously. And maybe I'll put that gaming rig on release preview, or something. In the meanwhile, I am, "on paper", a member of the insider program, and a believer in /advocate for the program, but am not really very engaged, nor am likely to become so again anytime soon.
Cheers!
