I'm loving it too and honestly the screen size is about the same as the Galaxy S3 but it's much thinner and smaller somehow!
And the 'smart keyboard' that was recommended by another android user is amazing. I now have all punctuation, good auto-fill and lets not forget smiley faces all in one keyboard screen! Don't forget to disable keyboard pop-ups.. they're just dumb. You can tap spacebar twice and it will add a period and a space at the end of a sentence. Nice touch. I will be buying the pro version for 2 dollars very soon to get rid of the ad interruptions
