I recently downloaded Google Desktop and I must say, it is one stellar piece of software. It is amazing to be able to search through all of my files and e-mails (Thunderbird is now supported!) in such a quick manner.
I think the coolest part about Google Desktop is that anyone with programming knowledge can create plug-ins to add to its abilities. For example, there is a plugin to index OpenOffice & StarOffice documents. Want to index other file types? All it takes is a plug-in to be created.
What a way to increase your audience. Microsoft would never do something like that, they are quite content on having it work with their applications only and if they must support other applications, do it in a half-assed way. It is too bad really.
I’m impressed Google. Keep up the good work!
