So here it is, v1.0 of the Mono framework, an open source implementation of the .NET framework for use on Linux, Unix, MacOS X and Windows system. Time to widen the gap again, Visual Studio 2005 Beta 1 (Whidbey) on your marks! Whidbey has been announced at TechEd Amsterdam, so look at some neat enhancements in ASP.net v2, new framework classes, clickonce deployment options with WinForms, etc.
Ah, competition keeps us sharp, forget about the religious discussions, let's create the best ICT solutions for customers!
