evince is wonderful and has kinetic scrolling. What was it that you consider it so badly ported? I usually read heavy stuff in it and I have no complaints.
I have few complaints about its functionality, but it's rather ugly, requires a stylus for some operations, and generally doesn't fit in. Also, as mentioned above, it lacks a discoverable fullscreen exit method, which means it would confuse the heck out of many new users. Mostly things like that. Maemo being reasonably close to mainstream distributions, a large amount of Linux apps will run with just a recompile, but their usability and level of integration will vary widely, and may not be suitable for mobile use without modifications. That's the issue with Evince right now.
EDIT: Hmm... I just looked down and realized I had Evince open, and furthermore that I was thinking of an older version of it when I wrote this. It's actually not as bad as I made it sound, but it still could use some work.
UPDATE:
@imperiallight: Yes, it has Rotate Left/Right options, and the operations are tolerably fast.
I've been switching between the built in pdf reader and evince.
Both honestly are ok but nothing great.
1) Zoom is clunky in both - no twist to zoom etc
2) On large PDFs page turns are slow on the built-in reader
3) Both aren't really finger friendly - I end up using the keyboard arrows
4) No search
5) No highlight or annotation
6) No wrap
I've ended up converting lots of them to html -but some scans don't work too well (all images).
Evince on the n800 actually works better.
My other complaint is the n800's screen was slightly larger which made reading a bit easier. The pdf reader is better than the ones available for android though if that is any consolation.
I have tried epdf but it was not really ported to a touch friendly interface, is evince any better?
Yeah, sorry. I put ePDFviewer up as an option, but it's not a very good one. I ended up not using that code for my own project so i don't expect to spend time fixing any of its problems. Evince is probably the best bet for a robust reader.
