You're missing the point focusing on the inaccurate descriptions of tech. The point, and greatest strength, of the book is in how people interact with the tech, and how it shapes society. Gibson has always been very good at articulating how technology shapes society, and the human response to technology, especially how people always find their own, unexpected ways to utilize technology (as in the famous line from his short story "Burning Chrome", "the street finds its own uses for things"). Frankly, an "accurate" description of tech would almost certainly just badly date it (e.g., "an unbelievable 500MB of RAM!")
