I know, microsoft is evil (trolling), but they’re really good for hardware. That’s why I bought this Microsoft Bluetooth Mobile Keyboard 5000!
Short summary of the french article: marvelous keyboard, easy to set up, comfortable, WIndows/Linux/iPad compatible. Available for only 40€ on Amazon France, and Microsoft is giving you a 20€ refund if you send them this coupon. So the real cost of the keyboard is only 20€, really good deal, sadly I don’t know if you can get the refund outside of France.
To conclude, it’s totally a keyboard to have if you plug your laptop on a bigger screen at home, really comfortable to type on. You should consider it too if you plan to build an HTPC, the keyboard is rather small and lightweight.
