It is usually just when Notch needs to update something I think recently as of March 9th the launcher is not working with the servers so they are trying to fix that.
you cant
Because chances are you don't have wi-fi, so the only thing you can connect to is your laptop or Ipod
If your Minecraft won't connect to any server simply restart your computer and the router.
It means you can not connect to the Minecraft servers, check your network.
You can. What are you talking about? I play on different servers all the time.
No. You cannot connect with other players with other versions.
Nobody knows.
This happens if the minecraft launcher can't get access to the minecraft servers. If you play the game from the website first, then you will get access to an offline version through the launcher
It's probably saying this because the Minecraft servers are down. Try again later.
Yes. However, offline servers do not require a real Minecraft account, but require Minecraft SP.
Yes it will you will be able to connect to the same servers as on the PC version.
You click "Add" or "Direct connect" and enter the server's IP.
