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).
