The 2009 release of Scrabble for the Wii is a family or party game based entirely on the hit word formulation game of the same name.
It brings in some pretty strange rules some of the time, and I've known the computer (You can play against a friend, or the AI) to bring a greek or spanish word into the game which, to my knowledge, was very contrary to the original rules of the game. Since the options aren't particularly customizable, and language barriers are very limited in this way too, I found no real way to turn this off, and thus, the Player vs. Computer mode was for me, rendered entirely obsolete.
You can play with up to 6 players which is always a good thing, and it does mean that you're not all crowded around the table. One drawback to the game's format though, is that every other player can see your letters, which brings up a lot of questions about the neccessity of gaming ettiquette, and also leads to the potential for many rude interjections from your fellow players. - "Why don't you put that there and make that word?" can frequently be used as a clever tactic.
Personally, I prefer the board game, if for nothing more than the greater tactical and tactile experience, planning your next move without anyone being able to guess what you might do. This port of a board game, a format which rarely works, takes away the capacity for personal cogitation, perhaps the most thrilling element of the game.
Scrabble 2009 doesn't really bring anything new to the table. Although there's a good high-score system and charming graphics and animation, about the only way in which this game is truly better than the board game is that you don't need to worry about any of your letter tiles sliding all over the board and making a mess. If you're willing to pay a tenner for this novelty than its your loss. Not really recommended.
