>Microsoft has the duo, the zune, surface pro x, the neo, basically every arm-based mobile product I've ever made has been abandoned, The windows phone.... The surface book appears to be dead. Continuum..

This is a dishonest way to put it for the bolded products, though.

• The Duo, as the article mentions, will simply not continue with two separate screens and instead will have one foldable screen. That's like saying they "abandoned" the Xbox because they released a successor product. They are iterating and changing the product, and we'll see if the name sticks or not.
• The Surface Pro X was just an ARM-based Surface Pro with an SQ 1 or SQ 2 chip, as it was refreshed in late 2020. It was not abandoned because the last ARM-based Surface Pro to come out came out two months ago, it's just in the same body as the x86 Surface Pro products now. You can get a Surface Pro 9 with the SQ3. The 9 simply merged the X and the regular x86 lines.
• The Neo never came out (and I'm guessing it won't).
• The Surface Book was superseded by the Surface Laptop Studio, which means that, similarly to the Pro X, the concept/product category changed/evolved with the successor, not that it was abandoned.
