Zenbe is a neat web application for the the web user who wants to keep track of all his stuff. What kind of stuff? For starters it can aggregate your various e-mail accounts and it has calendars and to-do lists. There's also a sidebar which houses the aforementioned lists, your address book, Facebook updates, and the latest tweets from the people you're following. Of course you can update your own status on Facebook and Twitter there as well. Zenbe has file storage so you can backup your important documents and photos, as well as sharing them with friends. I didn't even mention the "Zenpages". You can create these Zenpages to keep all your stuff related to certain projects or subjects and share these with friend or colleagues.
Zenbe does a lot of things and does it well, but its most significant achievement is that it does so in an exquisitely designed package. There may be a lot of clutter in your digital life, but you don't experience it as such when you put it all in Zenbe (Very Zen). Zenbe is free as in beer, so there's really no reason not to try it.
PS: Yes I do know I sound like I work for Zenbe's marketing department, but I really like the app.
PPS: If you have an iPhone or iPod touch with the 2.0 software you might also want to check out their Zenbe Lists app.
