Having blog-blasted Microsoft because my new Ergonomic Microsoft Keyboard 4000 stopped working after one week of use, I now have to praise them.
I took me a while to establish that I had indeed bought the keyboard in the USA and brought it back here (my fault for the delay, not theirs), but once that was done, they were amazing in their response. I now have a brand new keyboard that works beautifully, and the swelling and pain in my wrists has vastly improved. Microsoft staff were helpful, followed up everything, and the result was excellent, the matter solved quickly.
So, credit when credit is due – thanks Microsoft.
