Do you run the Magio under Windows or Linux?  If Windows, how do you deal
with the limited resolution of the M1?  

-Thomas

Primarily, Windows95. Quick answer: NTEmacs. 
Long, protracted answer:

I can't imagine full time wearable computing without Emacs. The
ability to have a single environment for most operations (mail,
editing, web browsing, ftp, contact manager, flashcards, etc) is invaluable. I
mostly use a 16p font for stationary work and an 18p font for
walking. Black text on light gray background. Once the font is changed for one app, it's changed for all (in
emacs). Switching between apps is easy, input tricks (completion) are standardized
across apps, built in customization through elisp, compiler,
etc.

I agree the M1 is troubling at first. When I purchased my first one in
June 1998, I sold it after a month of sporadic use and looked towards an audio
interface. About that same time I commited to NTEmacs on my notebook
computer and began the immigration process. Six months later I purchased
my second M1 and very gradually I moved towards full time use.

The difficulty with the M1 is due to 1. the
adjustment to a monocular HMD from a desktop display (monovision,
positioning, ergonomics, focus)  2. is dealing with low
resolution. 3. is the social factor.

1. Basic HMD adjustment takes -time- 1-2 monoths of frequent
use. Experimentation with different mounts. Monovision habituation.
2. Low resolution shock is minimized with Emacs. (for text applications)
3. Pretend that everyone you meet (and everyone around you) is a member of the wear-hard list
and what you are doing is nothing new :)

Even when the hires HMDs emerge, user interface (both input and
output ) will be a challenge.
Emacs gives us a wearable operating environment NOW, under GNU
liscense and an augmented memory application: Remembrance Agent.

The academics (CS people, in particular MITites) often have the
advantage of familiarity (if not expertise) with emacs before moving to a wearable - a
big advantage IMO.

I experimented with different wearables and interfaces at first(palm pilot,
pc110, TTS, voice wreck, dos, win3.1)  but most of what I am doing now
after struggling turns out to be what Thad Starner recommended in the
first place. For Monadic Wearable Computing (or dare I, Monadic
Somatic Computing) he provides some really solid advice for getting started.

<mode="nostradamus">Despite the <experience>promises of manufacturers</experience>, the M1 will be the
only reasonably priced, VGA input, low power HMD through the end of this
year and a will remain a strong budget contender thereafter.</mode>

You can download NTemacs through emacs.org

Oh, and Familiarity with NTEmacs should ease the Linux
migration.(remembrance agent)

whew!
