Living in the UK, and rainy Manchester at that, I'd hesitate to say we even
get much sunlight. However, I read a lot at work in my job (train conductor) and the experience of reading e-ink in daylight is much, much better than off an LCD screen.
Ive been reading ebooks since the pda days, some kind of Palm or Handspring was my first iirc. Reading on my spiffy new Sony 650 (replacing my launch 505) is most pleasant in comparison
