I need to get out more. So I am trying to untether myself from my offices, and I'd like to be able to perform as many of the standard tasks as possible via WiFi access or WWAN (cellular wireless broadband access). I've been investigating some web-based applications, looking for inexpensive and flexible alternatives to MS Office products as well as other useful web tools.

Of course, some things I've been using for quite a while, like Blogger, Gmail, and the personalized Google home page. Some others — Flickr and del.icio.us — I've played with, but can't quite wrap myself around.

A few notable tools I've found are listed below. I haven't worked with any of them long enough to form a strong opinion, but they all look promising.

• 30 Boxes: a public/private calendar application which can import form other sources
• Writely: a word processor & collaboration tool recently purchased by Google
• iRows: a sharable spreadsheet

Do you have any web tools to suggest? I'm open to suggestions.
