No, not me - the iPhone app. :)
I just downloaded the 1.1 version of Deep Green & it clearly adds more personality and polish to what I think has long been the most polished (and personable) of all the iPhone chess apps. If you've never used it, it's hard to imagine how much more smooth and stylish it is than the competition - but if iPhones came with a built-in standard 'bundle' of apps, this would certainly be the one to pick for a chess game. (See link below.)
Having said that, it doesn't have many of the features that serious chessers might want: You can't yet export your games via email. It doesn't announce openings. It doesn't show analysis. But if you want a slick looking & enjoyable app with which to pound out a casual game of chess on the train, I think Deep Green will make you very happy.
New in .1 is a great new set of analog sounds (including special sounds for check, checkmate, promotion, etc.), new animations, "callouts" (little speech bubbles that allow the pieces to 'speak,' announcing check, etc.), a Help system, an auto-rotate feature that makes 2-human games a snap, and more.
Check out this page for more information, and look at some of the demos you can run on the virtual iPhone to the right of the page; it will give you a good sense of Deep Green's game-play and sense of fun.
Cheers
EDIT: A little birdie (that's pretty much always a metaphor for Twitter now, right?) told me that the forthcoming 2.0 version of DG will offer support for multiple games, PGN, correspondence chess, copy/paste (PGN, FEN)... Niiice.
