And I'm just the opposite. I prefer the largest screen possible. I have a laptop and a Kindle, and much prefer reading ebooks on my laptop because I can get between 1.5 to 2 times more words on the laptop screen than the Kindle screen.
Lady Fitzgerald is right about the battery issue though. Reading on my laptop is great when it's plugged in, but on battery, I only get an average of 2.5 - 3 hours on my HP with a 12 cell battery.
