How is the iPod game Scrabble?

I like the game Scrabble, and now im thinking of buying it for my nano 4th generation. It's average rating is 4/5 stars, which is quite good I guess. What are the good and bad things about it? Do you recommend it, or are there better games? Please answer with your PERSONAL EXPERIENCE. iPod games are pretty costly, so I dont want to regret it. Thanks :)
