Now this looks GREAT! Maybe not as good at first glance as the M8, but......

Open source operating system (Linux)
They include a toolkit for disassembling the phone
They encourage hacking....both hardware and software.
Built in serial port (for hacking)

$400 is the supposed street price. We'll see.

I like the Qtopia Greenphone from Trolltech more. :P http://trolltech.org/products/qtopia/greenphone/index

Open-source, Linux and hacking is an integral part.
