There is - XCode. But it's only for Mac application development. In the comparison of VS and XCode, by someone who had only used VS, and in several other web postings, people said that it was easy to use. (Which may be entirely relative - I've never done any programming since a course in BASIC which I took about 25 years ago!!) Don't think my husband has tried XCode yet, though he did use Codewarrior which was a cross-platform development environment, but no longer works with Intel Macs. Were you looking for something cross-platform?
