Pros: I'm very pleased with Dragon NaturallySpeaking premium student-teacher edition. I'm a teacher at a major university. I ordered the software through Newegg. It came promptly and it installed easily. It requires University validation but my email address being an .edu one was adequate. I've used Microsoft's speech software. Dragon 12 is many times better.

Cons: I couldn't find any. It requires a lot of storage memory and installed memory, RAM needs to be at least 2G. I have 8G.

Pros: reasonable cost & compact

Cons: The ear bud was too large for my ear and thus didn't hold the microphone at a constant angle. The microphone thus could not stay at the optimum distance and angle for dictation.
