The full cost of a Pyra is estimated to be around €500 (~$565 or £388) for a normal model and €600 (~$678 or £465) for the 4G model. The pre-order cost is €290 (~$328 or £225) with the rest paid before the Pyra ships (date not finalised). So, yes, it's expensive!
The Pyra is the successor to the Pandora which was notorious for the lengthy, mishandled development and release period. However, the Pyra is being managed by the competent EvilDragon and developement has thus far been very smooth.
Hardware-wise, if the Pyra is anything like the Pandora then it will be an amazing and more powerful device. As with the Pandora you will be able to run emulators for Amiga, Atari ST, Spectrum, C64, PC DOS, Arcade, Neo Geo, Gameboy, Megadrive/Genesis, SNES, N64 and PlayStation and of course the Sega Dreamcast (amongst others and probably more modern machines) plus interpreted and open source games. There is also a full desktop Linux environment.
