I see +Renaud Lepage posting he has his, and I'll be +Tom Gray will have his soon.
The device is also making its way onto the 3 big carriers. All 3 are reporting that the devices should be ready by November 8th.
So if you missed your shot, you can just walk into the store to pick one up without a 2-3 or 3-4 week wait. Except... they'll be more expensive.
[edit: that price is $500 for the 16GB version, so that's $150 more]
What is kinda better is that you could get it on a 2 year plan for just $100. You'd have to be ready for an upgrade, or buy out your old contract. But 2 years, paying off $400... that's ~$16 every month to the carrier for the phone. I'd rather just buy it out right. No more ties for me.
[update: Videotron is also in the mix, but no word on price or timeline]
I'll be keeping track of where else you can buy the Nexus 5 over the coming days. Don't forget we've got a database of all the phones and prices (I'll embed below).
