It's a tad bit slow, but having 128MB of palm software on demand is awesome. I looked at pictures of InnoPocket adaptor and the matchbook adaptor. The InnoPocket adaptor seems to stick out too much out of the slot. This will create a problem with my fliptop case. I don't have an immediate need for the adaptor at this time, but I will defenitely place an order for a matchbook sometime in the next three months.
Customers are always RAM hungry.
What I'd really like to see is a new Handspring which uses wafer-thin 64MB SmartMedia card as RAM while leaving Springboard slot for functional uses.
