lastly I've been feeling like jquery is slowly becoming the defacto standard in js libraries I might be wrong!) or at least that is more active than the rest of the frameworks...

for example I've been looking for a fine open source calendar like componente and found http://fullcalendar.vinsol.com/

we've been using prototype for very little things, like its selector capabilities ($ function as a shortcut for document.getElementById, mainly), executing some piece of js when the page is loaded and to issue some very simple ajax calls.

so I guess the migration should be quite straight forward, but I'd like to know the pros / cons of migrating to prototype...

on the other hand, I guess that having both of them together is not a good choice, specially taking into account that the migration should be quite simple... am I right?

saludos
