Great article by Peter Bright.

There are lots of developers producing Mac applications and utilities. And they’re actually making an effort with them. Conscientious developers, who care about making an application that looks good, works well, and exploits the capabilities of the OS, are putting out great applications for MacOS X. We see applications like OmniGraffle, Adium, NetNewsWire, Delicious Library, Quicksilver, Coda, Unison… these apps are all well put together, a lot of effort has clearly gone into them, and there’s a real sense that their developers care that they don’t suck.

Windows software has never struck me as being like that. The third-party software ecosystem for Windows is big, no doubt about that. But it’s also incredibly shoddy. Most Windows applications—from both major software companies and minor ones alike—are ugly, poorly-thought-out, clunky pieces of crap. While there are a few artisan developers for Windows, most Windows devs just don’t care.
