I've been waiting for a 64GB Cloud White since launch day, and been madly refreshing the page since (even installed page monitor and iwantanexus).
It seems like I will never get my hands on one at this stage :< Only one store in Australia sells it locally, and it's the 32GB MB. I don't want to settle for a 32GB model, but I feel myself getting desperate to hold this phone in my hands.
This will be my first experience with Android, as I have been using iOS since the iPhone 3G. I bought a 6 Plus and wasn't impressed with the "upgrade", so I returned it within a week. The phone was $1200 outright here, and didn't offer enough features from my iPhone 5 to warrant the upgrade.
If I'm going to upgrade, I figure I want to make the switch to stock android and the Nexus 6 looks like a pretty nice upgrade (although the Note 4 has also tempted me, but ugh Touchwiz).
I hope the Play Store gets more inventory soon!
