Basically pretty much what the title says. The news on WhatsApp today got me thinking (I've never used it) that I need to replace my existing chat solution (GoogleTalk). There are many different ones out there like WhatsApp, Telegram, Silent Circle, Line, ChatSecure, Cryptocat, WeChat, Kik, Hangouts, etc.
I'm curious about anyone's experience with any of these and I think I'd ultimately like one that's more secure if the options are there. Also, I really need it to be compatible both with mobile devices and on the desktop in some form.
