Heck even keeping the laptop charged up may be difficult,
Get a cheap ereader or 7 inch tablet and the solio classic2 solar charger and you won't have any problems. My 7" tablet has a 4000mah battery and the solio has a 3200 mah battery to recharge it. I plan on maintaining my blog while on tour and I'll be taking 100's of photos everyday with my DSLR. It won't be easy but I plan on having downtime everynight.
