I think I'm ready to join the ereader crowd, and I've been reading reviews and looking over comparison charts and everything else. I've narrowed it down to either the Kindle or the Nook, and I was hoping for some advice or tips from people who have actually used them.

I don't need the 3g version of either, wi-fi is more than sufficient for me. Battery life isn't a huge deal, as long as it lasts a couple days I don't mind if I have to plug my device in every 3 days instead of every 5. I don't care if one weighs half an ounce more than the other, or is three millimeters thicker. I don't travel internationally, so any restrictions or limitations there don't matter to me.

I think I would prefer the physical keyboard of the Kindle to the Nook's touchscreen, but I'd like to be able to borrow ebooks online from my library, and the Kindle doesn't do epub. I realize that all of Amazon's ebooks are DRM-locked, but that doesn't bug me enough to turn to an inferior reader. It was a bit of a red flag to see the Kindle doesn't have an option for expandable memory, but on the other hand, by the time I get to 3500 ebooks, I'll probably be looking at getting a new ereader anyway.

I've also heard the Kindle's "turn page" buttons are in the way and get bumped easily. Are they really a pain, or are they easy to avoid?

I'd prefer the Android OS of the Nook to the Kindle, but I don't care enough for it to be a dealbreaker. I have heard that the Nook is slower to respond, and a bit glitchy, but that might have been fixed in firmware updates.

I would also like to know how well the internet-browsing works on both devices. I'd still use my laptop to do most of my surfing, but it'd be nice to check out a few sites on my reader (like RAFO). Is it just a gimmick that hasn't been worked out yet or are the browsers worth it?

Is there anything I'm overlooking? Any feature I'm making too big a deal out of? Which one would you recommend?
