All good suggestions. For smaller devices, I recommend the iSun solar charger. I picked one up at Radio Shack for about $30. It comes with 6 or 7 different adaptors, so a wide range of devices can be charged, including cell phones, MP3 players and Pocket PC’s. The power demand of a laptop is too great for the iSun, but it comes in handy for those less power hungry gadgets. You can also use an indoor light to recharge devices with iSun, so it’s good for rainy days too! Check http://www.ipsolar.com for more info.
