Well, I tried making rice both with softened (Brita-filtered) and hard tap water. Couldn't tell the difference.
I *did* detect a difference in texture with rice (I use short-grain) that was left to soak for half an hour before cooking. It was better, but I'd still skip the soaking if it was going to delay the rest of the meal. Often, I cook stir-fries or Thai curries which only take 15 minutes or so to prep and cook. Without soaking, my rice takes 20 (15 to cook, 5 to rest - resting is very important for the texture) so in those instances it's unlikely I'll prep the rice earlier.
I notice that proper rice cookers (e.g. Tiger, Zojirushi) take around 40 minutes to cook white rice, whereas my cheapo one does my one-cup in 15, so I suspect with a proper rice cooker the soaking isn't as necessary.
