Sorry to jump into this. But the IDE on the OSX (xCode) is not very good. It is cumbersome and heavy and ultimately fails in the most frequently used feature; editing text. I swear this part is preposterous, at this time. It is so bad that I have abandoned sing XCode (IDE) for editing text and instead use jEdit or SubEthaEdit and then edit the makefiles by hand. ;-/ The API (Cocoa) is awesome. It is really strange at first, after using C++ and C for years, to discover an API and language that are simpler than C++ and yet vastly more flexible than C. I still prefer C++ though. The integrated debugger (XCode) is finicky. First there are bugs in it that cause it to crash and it brings down the entire IDE, with all of your source code. :-/ Secondly it doesn't traverse variables very well, in my experience, especially stl stuff. So I end up using DDD, installed through fink (project that ports applications from linux to OS X). On OS X, there is CHUD; a set of tools that can prove invaluable when optimizing code. Hardware level debugging, including instruction stalls and branch mis-predictions and other cool details about the execution of your application and the system as a whole. > I wonder mainly because the time to compile benchmarks I have >seen of the Opteron are impressive. There are some strange things that Apple has done with respect to the development environment. For instance there is no dynamic version of the standard C++ library, only static.
