I have a D-Link DIR-655 that I haven't taken the time to update from the factory firmware. No traffic usage monitoring at all in the stock firmware, so I grabbed a "UPnP Gateway Traffic Monitor" applet that runs in Windows.

I'm using this: http://www.d-bross.com/en/downloads/

The software seems totally lame, but apparently the key phrase to search for is "UPnP Traffic Monitor" and there are a couple little cruddy things that will monitor your WAN interface in some way.

A simple not-quite-perfect fix for monitoring traffic, says I.

The Apple Newton is, in my opinion, a great example of technology living beyond its expected lifetime and abilities:

There's a very strong and active user community, plenty of help, and gobs of software. An incredibile amount of work has been poured into the device with addons like wireless networking, CompactFlash ATA support, Shoutcast and MP3 playing, web serving, and desktop synching. All this adds to the Newton's built in PIM, notetaking, and email support.

I use my Newton for a telnet client, guitar tuner, notepad/to-do lister, and MP3 player.

The first usable Newton was put out in 1996 and the most powerful and expandable Newton was released middle of 97. The thing's lived a long life and looks like its gonna keep on chugging for a long time more, expecially since they can be found for just over $100 on eBay and the continued support of the Newton community. I know I won't ever ditch it.
