Also, 64-bit CPUs do not run twice as fast as 32-bit CPUs.
Infact, the move to 64-bit CPUs isn't a particularly required or useful upgrade right now, especially for the average customer. In a 64-bit length of code, some of it is the instruction, and the rest is the data to be processed by that instruction. In some applications, having a long data stream is useful, like say database processing, but for many other applications, small instructions regarding small amounts of data is the norm. Even a well-implemented 64-bit port of an application may not yield signifcantly better performance, because at the end of the day, the amount of 'work' hasn't increased (ie. a bigger calculation isn't necessarily a better thing).
There is also little or no support for 64-bit CPUs, and Hyperion does not have the time or money to take on a project where not only a move from 32 to 64 bit code is required, but a complete change of architecture is also required.
It would be nice if AmigaOnes were better value for money, but personally I would rather see them be more expensive and survive (in a business sense) for longer. I think time has yet to tell for the A1 or Pegasos.
