You all miss the point.

Platform swap is not just about the cheap target hardware. It is about 64 bit support and changing the entire System API to support multi core/cpu and memory protection.

It makes no sense to just swap the hardware. This will still leave us in the 1 CPU with max 1,8 GB RAM hole with all its limitations.

Since every step as a result means loosing software compatibility this needs to be done in one go.
