As often with Individual products it's not finished and currently 1541 emulation does not support loading a d64, so it's pretty useless even if customers think it's similar to 1541U. Currently, it's not.
I guess Jens regrets it now a bit that he've made the Chameleon hardware available for an "open Beta", if he reads such silly posts. The Chamelon is still NOT an official retail product, and it was advertised in this way from the beginning. Look at Vesalia!
