Google Notebook

I just discovered Google Notebook, and it looks promising.
To use it you need a (for IE) 170kb browser addon, and if you want to give a look to a tutorial, you can go here.
The main use of Google notebook is to collect information ("web clips") from differente sources, mainly web pages. Then you can access what you collected, and organize them as you like.
The main thing to observe here is that this useful feature is... google-based!!! I mean that every single byte you insert into your notebooks is stored on Google computers - I do not mean that it can be considered "public", but I will not send my credit card number out there... ;-)

Let me know if you decide to use it, and your opinion!
