Hi All,

Just a quick addition to the points that John Panarese made about why the 
process of interacting for VoiceOver on the Mac is likely to stay around for a 
while  longer.  Interacting minimizes the load on your system by only 
loading/tracking those facilities that VoiceOver needs to use in a particukar 
situation. On the Mac, in contrast with your iOS devices, you are running a 
much wider range of activities, and have access to many more system functions, 
services, etc. -- whether or not you are aware of this, or consistently make 
use if this.  If you work on older version of Mac OS X that have VoiceOver 
loaded, or on machines with limited memory resources, it's clear there are ways 
to optimize your system's response and performance, both by which specific 
commands you use and how you operate.  The process of interacting actually 
helps you work well with the available resources.  It may be that at some time 
in the near future that typical memory resources, processor speeds, etc. for 
devices is such that there's no need for any kind of performance optimization 
when screen readers are used, and that the additional load on resources and the 
need for efficient usage is irrelevant.  But for the present, interacting is 
still providing an efficiency advantage to the way that VoiceOver works on the 
Mac. This is much clearer based on the experience of using VoiceOver on older 
Macs.  And by the way, I still run the PowerBook G4 laptop I had when I first 
joined the Macvisionaries list in 2005.

Cheers,

Esther
