In the 90s the market was new and fresh and nobody really knew what would sell, so people were gambling on many variations of product.

Now we know what sells, and it's an iPhone or an iPhone wannabe. Nobody wants to spend tens of thousands of dollars on something that isn't a phone, so nobody does the development to mass-produce these items.

Notice how phones were wildly insanely weird before the iPhone and very quickly afterwards they were all black slabs?

You'd probably have more luck cannibalizing the 200LX and shoving a phone inside it.
