Depending on the trips that you do, your style of photography, and I'd imagine electronics in general, the biggest consideration for me was battery life. Aside from the weight, extra batteries are very very expensive.
If it was me, I'd go standalone camera, cell phone w/GPS (but likely not even bother with GPS and get the lightest cheapest cell phone), and ipod shuffle (best sound according to audiophile forums). How my gear feels, accessibility etc, when I'm hiking is a big consideration for me.
Also my gear serves double purpose for overseas travel, in which I try as much as I can to combine with backpacking. I find if I don't want to worry about bringing along a charger with mulitple adapters and 4-5 extra batteries for a 10 day trip, battery life is a top consideration.
Running out of juice midway between a trip sucks.
Are you sure, you're not going to want better quality photos?
I don't consider myself much of a photographer either, but I'm often awestruck by the views and want to share/proselytize. I'm more of a landscape vs wildlife person, so a wide angle is actually more important to me.
Going off topic, I just bought a Kindle 3. Haven't received it yet, but battery life was a deciding factor. I read a lot travelling/backpacking, especially solo. Historically, I"m also a poor planner so I end up scrambling, looking at bus schedules etc. I chose the Kindle 3 primarily as a book reader, but also because it has a "useable" web-browser, and free 3G access in over 100 countries. The battery lasts anywhere from one week to a month depending on how you use the wi-fi/3G and it;s 8.7 oz vs at least 1.3 lbs.
I guess what I'm trying to say is: have a good idea of your intended use for electronics, and your proclivities, but in the meantime, you can't go wrong with using battery life as a top criteria for selection whichever way you go.
