Whatsapp is awesome, not having to sign on or add contacts is reason enough to buy it. Plus all the other features make it a no brainer. I hope the app gets bought by apple and rebranded as iChat for iPhone, the integration is great, this type of thing should have been offered by apple from day one.
I love being able to send pics over data/wifi as opposed to mms, also sending your gps location is handy. That reminds me of a demo video for the nokia n95 that I watched years ago, people hanging out sending their location and their friends using the data to get directions.
