What's cool about skype
For Rob: (No, I won't bother registering in a site to be able to post a comment, so this is easier).
Without even considering the political stuff, which I don't give a damn about, here's what I find nice about having Skype in Linux:
You can use skypeout and call long distance or international very cheaply
You can replace your company-wide phone system with it (or never bother to install phones), although I prefer to use {gnome,net}meeting or ophone for this sort of thing.
It does work from behind a firewall, which is what hasn't let me use MSN or similar AV systems.
Since it works on Linux, I can use it.
Of course all this assumes Skype works as advertised. But if you know of an alternative that can do all that, that would be even better!
I agree that for local calls, if you have little need for a phone, it may make no sense. Sometimes. In some places, local calls are free. Here, I pay by the minute.
Skype would save money in some cases, when I need to have a two-hour-long talk with a client.
In short: would I prefer to have a free, open source program that does all the above? Sure! (although I can't imagine how Skypeout could be free).
Would I prefer not to have Skype? Hell no!
So, while not ideal, it's good. And if it's good... well, that's good, isn't it? Then why gripe?
The other thing is that it manages to pull good quality audio off very poor bandwidth. I'm not sure what codec they are using but it kicks butt.
I agree with Taj. While voice-chat options have existed on standard IMs for a good while, skype quality makes it really worth it now.
They use iLBC.
Skype is a sad thing. Why, oh why, do you use an application which business idea is to compete in the VoIP arena with secret protocols and proprietary encryption?
Use kphone! If you just want over-internet calls, set up (or use any of the numerous free) SIP proxies (ser is a hundred k, asterisk is a bit larger). If you want a real phone number, you can buy that too, much cheaper than POTS (that's something Skype doesn't even offer!).
