- Does the app have a full screen mode that removes the frame?
- Can I tap on the screen and turn the page?
- Does it have a multi-column mode?
- Are the settings menus usable from the touchscreen?
- What about pinch-zoom?
- Useful - Kindle, Adobe Reader 9, Mobipocket
- Marginal - Kobo, FBreader, Nook
- Useless - Blio, NookStudy
While this is possibly the best app for a laptop, it's useless on a tablet. The only needs it fills are the full screen mode and the 2 column mode. The general design is intended for a mouse, not fingertips. Also, there's no way out of the full screen mode if you don't have a keyboard or mouse. (Fortunately I have an onscreen keyboard.)
Forget about it. It's not completely useless but it come pretty close.
This one is usable. It has a full screen mode, but just the single column. The touch friendly menu gets a passing grade, but only barely. It feels like the design just happened to work with a touch screen, not that it was designed for one. The page turn gets another marginal grade. You can't just tap anywhere on the side of the screen to turn the page; there are 2 small dots where it will work.
Surprisingly, this one is more useful than its sibling. Perhaps that's because it does less? Anyway, this is much more fingertip friendly, but it's still only about as good as the kobo app. It does support full screen, multiple columns, and it has a reasonably good menu design.
This one is a mixed bag. It supports tapping the screen to turn the page, but the settings menu is impossible to use with fingertips. The rest of the menus are somewhat usable.
Adobe Reader 9
This is very tablet friendly and it has most everything you'd want, including pinch zoom. It doesn't really like screen rotations, though, and I can't find the reflow mode (it's probably there somewhere). But it's good enough that I don't see a need to get another PDF app.
I've been wanting to try this on a tablet ever since one of the updates said it supported Win7 tablets. it did not disappoint. this is the app that I measure everything else against, including Adobe Reader. In fact, I'm using the Duo as an ereader right now with this app.
This was a surprise. Amazon abandoned MobiDesktop back in 2008, so I wasn't expecting it to work very well on a tablet. But it's rather useful. It has a full screen mode and it even support pinch-zoom for changing the font size. It also has more font, formatting, and annotation options than the Kindle app. Unfortunately, there's no easy way to get out of the full screen mode.
As you can see, you do have some options for reading on a Win7 tablet. If there's an app I missed, please feel free to suggest it. I deliberately skipped some PDF annotating apps like xournal. (That one wouldn't load a PDF, which cuts it out of the running for reading apps.) I'm planning to cover the PDF annotators separately.
