I like the S Translator, although it remains to be seen if it is as good as or better than Google translator. I like all the software enhancements of the device! Not too sure about the tilt scrolling...
Whoa that's a tough one...there are lots. Air gesture, pic w sound (I can see myself texting a pic saying “duh" to my friends or a million other goofy sound pics), the slightly smaller size but bigger & better display.
Edit: I can't believe I forgot to mention the remote control feature...that will rock!
