The WaveLAN card does have a power saving mode which, if enabled on my
Windows notebook, seems to increase the battery life considerably. At least
part of the power saving seems to be achieved by dynamically switching the
card between 2 Mbps and 11 Mbps modes as required. Hopefully a power saving
mode can be implemented in the Newton driver in the future.

Incidentally, I noticed that there is now an alpha 3 version of the driver
available at:

http://www.ff.iij4u.or.jp/~ngc/eng/newtwave.htm

This fixes the problem that the "old" and "new" drivers both needed to be
installed and works very well for me. I'm very pleased that this driver is
now showing such rapid improvement. Kudos to Hiroshi!

My personal wish list for the next "iterations":

1. Network name configuration
2. Network password configuration (i.e. enabling WEP)
3. Low-power mode

Simon
