Paint.NET is one of the best image editing applications for Windows and it has a version for Linux too, called Paint.Mono (or Mono Paint). According to Miguel de Icaza, most of the features in Paint.NET have been ported over to Paint-Mono, with more to come. Apparently, this should also work on Mac OSX, details HERE.

Addressing a new danger that the GIMP gets replaced by Mono, by default

Canonical's Gerry Carr said that Ubuntu was not deliberately looking for Mono-based applications nor is it excluding them. The Canonical Board has yet to make a policy decision on Mono. He said that there will be one more piece of Mono based software called Banshee in 9.10. Banshee is an audio player and might replace Rhythmbox.

GIMP bitten by a C&D and responds; why Mono is different

A bizarre decision is made just weeks before the final release of Ubuntu 10.04 because an F-Spot (Mono) competitor is removed and Banshee (Mono) gains integration with Ubuntu One
Steven Rosenberg has just published a rave (finally!) about Ubuntu 10.04. He particularly likes gThumb, which can help remove Mono from Ubuntu.

Mono loses ground as it gets increasingly removed and Ubuntu should follow suit (regarding Mono inclusion), argue some of its own users

Mono has a potentially fatal sting-in-the-tail for some, and leaves a rather nasty taste in the mouths of many others… So, I thought I’d see what happened if I removed Mono from Ubuntu.

paint-mono is a port of Paint.NET. The only way it could be built in the past was using a development version of MonoDevelop and there was no way of generating packages for it.

There has been a lot of pro-Mono and anti-Mono arguments assaulting the community of late. The debate is not new but both sides have taken up arms since some distributions have decided to either remove Mono or include Mono by default.
