Sure, it would be cool to have a hardware-hackable phone, but I don't see it replacing most of the niches the RPi does well:
* Leave one in the basement or the garage logging data from some sensor
* Give one to a kid to hack on
* Play around with using it as a server, as a media player, as a mini-workstation
Yes, most phones are more powerful than a Raspberry Pi, but no one is using a RPi because it's the most powerful thing out there. It's cheap, hackable, and separate from our other devices, but can be networked with them.
