Something to Investigate
I'm a big fan of Dave's Quicksearch Taskbar (I don't like third part toolbars on my internet browser. And this little tool on the taskbar works out nicely.), Gmail, and Bloglines (although I still use a rich feed reader on my primary machine).
So what's this A9 thing? Do I want to put my Favorites list online, so it can be accessible from any computer? It'd be difficult for me to add a blasted toolbar to my browser, though...
What all do I want to keep on individual machines, and what all do I want to make accessible everywhere?
