I think it's time to rethink the nature of the tests. Open up the calculator restriction to any model that is not networked in any way.
My kids are in high school now and it seems like what the tests are really measuring is the ability for the kids to take a test. The SAT feels especially useless as an indicator of anything other than that.

College Board also wants to make it difficult to copy down exam questions that could get reused. For this reason, calculators with QWERTY keyboards are banned. Evidently there is no problem with DVORAK, and nobody would ever learn to type quickly on an ABCDEF keyboard.
