I just got a "certified like new" d1 from verizon, it was a warranty replacement free of charge. It looks brand new and I'm happy with it. Only thing I've found is the screen wiggles a bit. Meaning the slide out part. No big deal to me though. All in all I think refurbs are fine.
I just got a replacement D1 from asurion as well. Mine was brand new but didn't have sd card. I had to call back but they offered to send car charger as well as sd to make up for it
So are most people getting Droid 1 refurbs as D1 replacements?
After much research I can only find news articles online saying Droid 2/X replacements, but it seems to be the same article copied by all Android News sites.
