Nope! I do sequential reading on my Kindle books. My use case for the Kindle is "Books I want to read, but not good enough for hardcover, and not referency enough to be put on the PC for searching"

Do you have an opinion about what size Kindle (e-ink) is best for Web browsing? You'd think the DX would be better, but what about the weight?

I wouldn't recommend trying web browsing on E-ink, unless it's through some Readability filter or similar. The screen updates are too slow for it, and the DX browser didn't render perfectly. I suspect the CPUs don't have the oomph for the modern web.

Note that my experience is on a 2010 vintage DX with no WiFi - it is limited to 3G on Amazon's dime. In Europe that's only Wikipedia and the Amazon store.

Thanks. Reading from LCD screens gives me eye strain, so I was thinking of reading blogs, news and software docs on the Kindle. Do you think that might work?

My local Staples sells Kindles. I would suggest digging a physical one up and flipping through it for a while.

I'd advise searching a bit for people describing their use - I suspect most 'send' material for later reading to the Kindle (through readability.com or some equivalent process).
