And now we see another good reason for Microsoft to not release the Surface mini tablet. ITWorld reports that Lenovo has already stopped selling its two smaller Windows-based tablets in the United States because there simply isn’t any demand for them. The decision comes to yank the smaller Windows tablets even though both of them — the ThinkPad 8 and the Miix 2 — haven’t even been out for a year. That said, there is a bright side here: Lenovo says that it is seeing some strong demand for its larger Windows-based tablets such as the ThinkPad 10 in the United States while also noting that demand for the ThinkPad 8 is strong in markets such as Brazil, China, and Japan.
