I haven't used a Kindle for it, but in general I find web browsing on an e-ink display is an incredibly subpar experience. No color and the slow refresh rate is fine for books, but pretty bad on content rich web pages.
E-readers only do one thing well, and that's reading books. But that's reflected in the price. The cheapest Kindle is $120, almost 1/5th the cost of the cheapest iPad.
thanks! it did seem to be too good to be true. I'll have to cont to lug my laptop around. so funny it seemed so sleek and shiny and new a few years ago! it's hard for old duffers like me to keep up . . .
