This new keyboard is really tough. But good. The only MS hardware I'll voluntarily buy - and I got it slightly used on eBay. The guy from Tennessee who shipped it shredded a bunch of styrofoam packing material into large chunks, and just tossed the keyboard in. When I got the box, it had a very ominous plastic (hard keyboard plastic) rattle to it. Luckily, just the left Alt key loose. Works fine so far.
