I've got the x. It is pretty big but I'm 6'2 so it really fits perfectly in my hand. Texting/typing is amazing with swipe. Its so fast and accurate. Half the time I won't even know how to spell the word and it will still come up. Battery life is good as long as you don't play with the phone constantly(hard not to do). Just using it as a phone it will stay up for a couple days but I normally have to charge it every night.
