Whatsapp

Many people have asked if I've "Whatsapp" and asked me to get one. While it seems to be really cost-saving as compared to SMSes (and I have to admit it is a wonderful invention), I don't think it is necessary for me personally. I don't want to be so "contactable" and bother myself with so much social networking stuff. I'll only get if I find it really necessary, for family/for you (hope we can keep in touch!)/for work. :)
