We've mentioned Path Finder, the full featured Finder alternative from Cocoatech, a number of times here on TUAW. I am sure there are a few of you that were upset because the latest version of Path Finder only works with OS X 10.4. The MacDevCenter sat down with Steve Gehrman and Neil Lee, the men behind the app, to talk about the decision to only support Tiger with Pathfinder 4.
They both make compelling arguments for Tiger only support (mostly they wanted to include the latest and greatest Cocoa features, and since there is only one guy coding it didn't seem sensible to support two different versions of Path Fider, a Tiger specific version and a pre-Tiger version). Well worth a read, if you are interested in Mac development.
