I also don't see what's "lazy" about the Add/Remove program panel. At least it exists. At least there's one centralized location for handling these things. OS X just rides on the old "oh, it's so easy on Mac, you just drag the app to the trash" which stopped being the case many years ago. These days installers scatter files all over the place, and there's no unified process for uninstallation. Some installers put an uninstaller in the Tools and Utilities folder. With others you have to download the app again just to dig out the uninstaller, and some simply don't have an uninstaller at all, but either way you can always be sure that there's tons of leftover garbage in various /Library and /Username/Library folders -- some of it may even be harmful. I remember uninstalling the driver for a Yamaha 01X audio device, there was a script but it was missing a couple of entries, one of them being the MIDI driver for the 01X. Upon restart I'd get a blue screen for 20 minutes while this orphan MIDI thingy was keeping the iMac in limbo before I finally arrived at Leopard's login prompt. Took me a day to track down the culprit, some silly little <500 kB file.
