I'd rather have a more complete upgrade than just a memory upgrade, the cd32 is a nice convenient size
I wonder though how many people would want an upgrade anyway, indeed it's very doubtful that there'd be 1000 people wanting to buy one of any kind.
The passive adaptor sounds interesting too, but if I'm going to upgrade the cd32 I'd really like an internal hard drive.
Guess it boils down to "how much" and "how many"
