Here's what I have:
The bad:
- Stanza is not usable in full screen mode - fonts are aliased badly because the zoom didn't properly scale fonts
- Same thing for B&N.
- Same thing with txtr.
- No white on black mode (night mode) in Apple's iBooks application
- It's kind of heavy in comparison to other book readers on the market.
The good:
- iBooks looks great, has bookmarking and dictionary. Easy to "highlight" words.
- I love the interface in iBooks - it's extremely responsive. The page turning gesture is very fluid.
- Search in iBooks is impressively fast, and the interface is extremely simple to use.
- iBooks has a dimmer.
- Kindle app works well.
- Kobo app also works well.
- Unrelated - but Netflix is awesome.
- Importing books into iTunes is extremely simple. I just picked up the folder my Kindle library was in and dropped it into the Books section in iTunes. It recursively found all ePubs. It did not add any PDFs.
- The ePubs of comics I made in Calibre look fantastic on this screen.
In general, I really like it. My biggest issue right now is the lack of Stanza. Since iBooks has no night mode, I really don't have a reading application right now that I can (happily) use for non-DRM ePubs.
Edit: I'm now using readMe to download books from calibre server. It works just fine for non-DRM ePubs, and has night mode.
Any more questions?
