Don't let the title fool you, this app is fun. I use to be a huge fan of scrabble when I was a kid. When a scrabble-like game came out of facebook, I enjoyed that too. Now with Words With Friends I can play a word game on my iPhone.
The game allows you to play with friends, strangers, or just take your time and play as a single to challenge yourself.
Reading the comments it sounds like they've been working out some bugs, which happens!
It's funny how new technologies can help revive the concept of a game that had long since become near extinct! There are plenty of games and iPhone applications at the iTunes store that have done just that.
Again, combing something retro with new tech... I love it!
