The calls have excellent sound quality and are highly secure with
end-to-end encryption. You don't even need to configure your firewall or
router or any other networking gear.
Additionally it doesn't just work on Windows. Skype is also for Mac
OS X, Linux and PDAs using Pocket PC, with a native look and feel for
each platform. Talking, sending instant messages or even file transfers
work between different platforms like a charm.
