Yes, Motorola used to be a high quality American communications company. Im old enough to know that (gulp)
If you buy a Motorola cell phone it is made by Chinese owned Motorola Mobility, subsidiary of Chinese owned Lenovo. Both Chinese corporations as you said. Sorry I know you know this I was just spelling it out for others in here, so they dont convolute that somehow their Motorola cell phone is American.
Lenovo is still somewhat complex. They were a big company before, but their position in worldwide computing is a result of their purchase of IBM's personal computing division. I had a coworker who went to Lenovo's development labs, which were (and still are) in North Carolina, where they took over IBM's previous PC operations. And with the purchase of Motorola Mobility, Lenovo is still employing R&D in Illinois.
