Haven't these people heard about HIPAA? You can't just transmit personal health information over arbitrary text message networks. It doesn't matter if they have a "secure server" somewhere(*). The whole network needs to be secure and auditable. And something tells me that this isn't the case for text messages.
(*) Google can find exactly two mentions of text4baby and HIPAA, both of which just say that there is a secure server.
That's just plain wrong. IBM opened up the architecture of the PC, so that anybody could make compatible products. Some engineers at Texas Instruments, frustrated by the shortcomings of the "nearly compatible" TI-PC, started Compaq. THAT is why we've got so much variety in the computer industry. Microsoft was just willing to sell to anybody.
