The design could speed up embedded applications."

Compared to a hard wired chip, we got something controlled by software. And a lot of Devices that likes to be jail braked.

waterproof phones? My Motorola Defy is good and all, but those rubber plugs and the seal around the battery cover can only take 1M of water pressure.

a SIM contains a cryptographic signature and some other things.
It's basically a watered down TPM that has a unique ID, a few kilobytes of storage, and a cryptographic key set.
A physical device like that makes it difficult to replicate the functionality of the SIM card, making it harder to make one device use the credentials and system identity of another device. (EG, it makes it harder for an attacker to steal your network identity and make lots of 1-900 number calls, which will then show up on YOUR bill, amongst other things-- like framing you in a murder by making all his calls with your number, etc.)
Making this an easily reprogrammed internal chip makes that physical level of security go away.
That's a bad thing.
Sometimes being inconvenienced is really in your best interest.
