Cons

The official plugin page on Launchy's homepage hosts just 11 plugins.
Con Abandoned
Launchy was last updated in 2010.

There are dozens of extensions, which is good, but as an average user it is hard to find what you are looking for. It is unclear to me how updating plugins work.

Currently, extensions can run only when you type their alias and <space>. There is no way to see results from multiple extensions at once. The output is also limited just to rows.
