This isn't an advertisement, but you might say I am addicted to Words With Friends - A scrabble game for the I Pod Touch.
You can see the board is getting full and my letters are getting difficult to use. I do have a word in mind, but I'll have to wait and see the next move by my opponent.
If anyone out there wants to have a game with me I'm Birdie1954.
There is a free version, but my son gifted me this paid one.
