I just played around with Google Labs’ latest release: Notebook. I was a little suprised that I was able to instantly start using it since most of Google’s new releases fill up quickly and you have to wait for an invitation e-mail.
Don’t get me wrong. I love Backpack. But it’s not totally free. Sure, you can have three pages or whatever it is for free, but Google allows, as far as I can tell, unlimited pages as well as the ability to add images, a feature that the free version of Backpack does not.
I also like the feature that allows you to instantly add “clippings” from pages you’re surfing to your notebook via a browser extension. Google Notebook also features awesome and easy drag and drop AJAX.
I can see how you could use something like this as a del.icio.us type app, but I don’t think that that is it’s best use. It’s better used as an organizational type service, similar to Backpack.
I hate to bail on the little guy for Google, but when the price is right, you gotta do what you gotta do.
