Existing Newton going FW4 to FW5, features lost?

[kenf]

I understand what's added when going to FW5, but I can't find a succinct list of what's lost. For example I understand that profiles can no longer be selected directly from the unit but must be done through Isaac, is that right? If I have TSS/NP etc is that lost as well? Can you point me to a list of changes or provide one?
Thanks,

If you're upgrading an older Newton (manufactured prior to October 2014) you won't lose the capabilities you've asked about; you can still enter Setup to make the changes you want.

The only thing that will be lost is if you have the "PowerPak" upgrade, or a "Zuuum" unit. Features particular to those two versions will be lost.
