[Reader-users] models

[tribble]

Greetings and happy holidays!
I just caught up reading the mail from this list over the past couple months 
and have a question.  Apparently model A of the reader, which I have, needs 
to be recalibrated after long unuse due to putting settings in volatile 
memory.  My question: Is model A going to be phased out? if so, can I 
exchange it for model B without significant cost? alternatively, can the 
firmware be updated on model A to make wiser use of the memory?
If model A is going away I am rather annoyed it was the only model sold at 
this year's convention.  It was nice getting the convention discount, but I 
would have gladly paid a little more for something that would be supported 
longterm.
Finally, I went to knfbreader.com and notice that there hasn't been a new 
release in a while.  Is a new upgrade coming soon?
Good to read everyone's comments.  This is a very informative list.
Thanks in advance!
Rich blessings...
