I love 'em, apart from the depths of winter when I wear fully fingered gloves, I spend most of it wearing fingerless ones. At home too when it gets extra cold and I don't want to put heating on, I slap them on and I can still do stuff with my fingers.
Have about 5 pairs of them, two are synthetic and pretty thin though, as I wear them for running. (edit: I do realise this sounds surreal "you wears gloves for running????" )
