I travel a lot for business. And as a road warrier, I am leading edge with electronics... laptop, Blackberry, iPod, etc. I use the Blackberry as a modem in out of the way places.
I have a tent trailer with a sophisticated solar system, and often go camping and use the trailer as a remote office (i.e. my company is paying me, they think I am in my home office... I am not deceiving anyone, as I am paid on producing quality work, not sitting in an office).
So I will echo the comments... UL solar is not there.
I would throw this out there though, given that I am wired to the world about 280 days a year. When backpacking I leave the technology behind. The only thing that is battery operated is a Photon light. I prefer this. Years ago I took a walkman with me a few times. I found the music distracting, even at night in my sleeping bag. Just some food for thought.
P.S. My 80 gig iPod has 1,000s of songs on it... including a huge collection from the 1960s that I copied from my 400+ LP collection. So I love music.
