What we said: 

Sales of PC keyboards and mice will decline severely over the next decade, regardless of what happens to the general economy. Laptop computers and tablets have gotten both cheaper and more capable. Even in emerging economies such as India and China, PC makers are focused on making and marketing cheap laptop computers. It isn’t hard to imagine that 10 years from now Logitech’s main customers will be enterprises, because they will be the last ones buying desktops. I am sure that Logitech's sales numbers will not miraculously bounce back… they are guaranteed to trend lower.

What happened: From the date of my blog post, LOGI shares declined from $21 to $7, a loss of 66%.
