what color should i buy? will white color turn yellowish? or go for titanium grey?

since i have wifi at home and office, would it be smart for me to buy Gnote II without data plan? if i need to travel outstation once in a while like once per month and need internet access i could just subscribe to Celcom Daily or weekly which is still cheaper than having a data plan.

i think if Samsung made Gnote III waterproof it would be perfect for me because often i bring phone to toilet and if possible browsing while bathing. hopefully so it will extend my boring shower time to more than 5 minutes.

does it really automatically take pictures upon hearing the word "cheese"?
