Stableboy Selections (a blog I should read more often) provides us with a fairly simple case for shorting Logitech. After joking about their domicile (Apples Switzerland) he points out the obvious - laptops are replacing desktops - pads and phones are replacing both of them. Logitech sells peripherals. The new technology (along with things like Google speak-to-search) will reduce the need for peripherals. Peripheral sales should fall year-in-year-out - they have done so at Logitech.
