I think Amiga Anywhere is an integral part of Amiga Inc. strategy to revive the Amiga platform.
The single biggest thing that stops people from changing platform and\or OS's is that thier applications are likely not to be able to run.
With AA replacement applications could be written for AA so they can run on these systems and allow a change over to the AmigaOne much easier.When the time comes, they can use that same software on the A1.
When AA and OS4 integrate, AA aplications are supposed to run natively, which should in turn boost performance.
If it was not for a string of companies pulling out of contracts with AA under mysterious circumstances, we would be seeing AA on 5 different devices already.I just hope the future track record will be far better than the past.
