I'm ready for it and I'm ready to leave Verizon for it, which is another whole section why I'm tired of my GNex on Verizon. I hope Google will do their own carrier alongside the xPhone.
I'm willing to bet my Maxx HD they're going make the bone headed move of low storage capacity and not a Maxx quality battery. In other words, what they always do (Google) have an awesome phone that gets crippled by a WTF? Decision.
Google wants to push people toward the cloud, so the deal breaker for me will probably be lack of storage (micro-sd or otherwise).
I have a 64gig micro-SD card that seems to work pretty well with my Rezound, but none of the phones I've seen (new or otherwise) report to support it.
