With the release Firefox 4 looming (early 2011) and the fact that as of yet our Modified Google Notebook Extension is still not working with the current Beta versions it may be wise to start considering alternatives. I know, I know, we all love Google Notebook, but if the day that we have to change services is not coming soon, I am sure it will come some time. So what alternatives are there? This may depend on what you use Notebook for.
Zotero
If like me, you are a student and you use Notebook for grabbing snippets from the web, names, dates, links, citations etc. Well I think Zotero is an excellent replacement. In fact I am using it now more than I use Notebook. Zotero allows you to grab pretty much anything from the web, whether it be text on a webpage, a PDF or video, sort that content into a folder and keep it stored in the cloud, for free (well 100 mb of content for free). They even offer integration with OpenOffice.org (and naturally NeoOffice, LibreOffice and Lotus Symphony)

Evernote
For those of you who have looked into alternatives in the past, you will undoubtedly have come across Evernote. It is certainly champion in the field of note taking and collecting information. It has a stack of features and it aims to make your information available everywhere and in order by doing auto categorisation. It also has a neat Google Notebook Importer. Personally I have always seen Evernote as web clipper, taking snapshots of webpages and most of its other features are left to its desktop applications (Windows and Mac, for Linux try NeverNote).

Zoho Notebook
Zoho has always been then closest competitor to Google's Office applications and their Notebook offering is definitely the closest to Google Notebook in regard to functionality and features. For those for you that want to transition quickly and without learning a new interface and new features, Zoho is probably the one for you.

The joy of Linux!
If you are a Linux user like me, you may be aware of Tomboy and Gnote. Both applications are basically the same, Gnote being a rewrite of Tomboy in C++ for those of us who are not to keen on Mono which Tomboy is born out of.
These are two very simple to use note taking applications straight from the desktop. And if you are an Ubuntu user you can automatically synch your Tomboy notes to your Ubuntu One account to access them anywhere online or to keep several PC's in synch (syncing it not available in Gnote yet).
So check them out:
Linux, what's that then? http://en.wikipedia.org/wiki/Linux
And, Ubuntu? http://www.ubuntu.com
Ah right, so Tomboy: http://projects.gnome.org/tomboy
And, Gnote: http://live.gnome.org/Gnote
For OS X, em sorry I'm a broke student and I don't like being told I can do anything I want with my Mac as long Mr. Jobs says so.
