Still I JUST bought a Roccat Kone + last week for a box I was building for mom's birthday. Nice mouse. Okay, there is nothing about fair trade mouses here (there is none besides Nager IT) but well, you can't have everything. And it's totally overkill for mom but I knew they had Linux support and the design is made iirc in Hamburg (.de) so I wanted to support that. And it feels nice under the hand, not too small.
Anyway, Logitech has a big market share and the HW is normally of good quality (used that brand from the early DOS times) so it's good if they become aware of Linux even though they should have done this much earlier, especially when you see how MS badly f*cked them earlier in the business.
