The online sales may have failed, but HTC and Google came out with a great piece of hardware. I've had mine for three months now, on AT&T, and wouldn't trade it for any other phones on the market; at least not yet.
It will be interesting to see if it will be the first phone to get Gingerbread (Android 3.0) like it did for Froyo (Android 2.2). The bump up to Froyo is fantastic.
The sad part is that we will see the end of open Android phones; the carriers really don't like people to root their phones and side load apps. Not sure how that effects development on those phones. Normal phone users could care less about that though, and frankly that is who they need to sell phones to.
Looking forward to what Google recommends for the next reference platform going forward past Gingerbread. I'm hoping that they have a dev version of one of the commercial phones that they will sell through dev channels; I'd pay the extra for an open version of the carriers phones.
