  1. Intellij has a free and open-source community version that is quite enough for my every day work (j2ee dev).
    And I just love it !

  2. You might want to add SharpDevelop and WebMatrix to this list, they are fully functional replacements for Visual Studio.

  3. I like a lot Qt Creator. It work in Mac, Linux and Windows. Great for C++.
    It can be used with Qt framework or not.
    For windows support both Mingwc and Windows SDK 7.1
    For C++ I would recomend this IDE.

  4. XCode? Nope, Xcode 4 is no longer free, unless you go for the earlier versions (3.x)… and your iOS apps will never make it beyond the iDevice simulator unless you pay 1000$ for an iOS dev licence.

  5. Xcode (as of v4) is no longer free. To obtain a copy (legally) you must now part with a whopping $4.99 (IIRC) – or subscribe to Apple Developer Program.
