Actually, I doubt that's the case. Based on my own experience writing
code that does the very calculations that the new Paradigm will do
(actually, my code does more), I would guess that the entire increase
in memory usage would be far less than 10k...likely closer to 5k or
less. Storage of preferences and settings will definitely be less than
1k, and the code itself isn't much. System resources really aren't
increased for the RF functionality with the meter, since the RF code is
already in the 511 in order to support the remote. The only additional
code there is how to differentiate the signal and data, which doesn't
take much at all. And, the 511's mechanism already supported .05
increments in insulin delivery, but it wasn't enabled in the software.

Actually, given all of the testing and approvals that are necessary,
$450 seems reasonable. Testing alone can be costly, especially the
amount of testing that would be necessary for a medical device, not to
mention administrative costs for just handling the exchange.
Further information that supports the fact that the Paradigm 511 and
512 are the same pump from a physical standpoint comes from MM's site
1. They no longer even offer the 511. The 512 is the only one
2. The "Paradigm Pathway" program, which is how you upgrade your pump,
says on MM's site, "Factory certified/exchanged 511 Paradigm pump with
Notice that it doesn't say you will receive a 512 pump, but will
receive a certified/exchanged 511 pump with the 512 functionality.
This means it is a software upgrade to the existing 511 pump instead of
a brand-new 512 pump.
