Daily beater. Can't go wrong. The barometer is a nice touch and can be used to tell if the weather's on its way down or not - the altimeter is only useful if calibrated. Doesn't need much charging. Has never showed anything but H charge.
As others have said, it's a more mustard / JCB yellow than the sunshine yellow it looks like on the photos. Reverse LCD can be a little hard to read in poor light and the light doesn't illuminate the LCD, but does illuminate the hands very well.
As title really, what you'd expect. The software that lets you schedule events when docked / undocked is a nice touch. Would have been nice to have an audio connector as well but as the phone doesn't have one on its pogo pins.
