Pampuk - thanks! Ease-of-use is the main focus of the next significant update (2.2), though certainly the other things you mention are possibilities too - we'd love to license a good textbook series (for iPad especially). We've already found a number of French dictionaries we can license, the problem is whether we'd get enough sales to justify the royalty advance we'd have to pay - German was much easier since HanDeDict is free (there don't seem to be any equivalent free Chinese-French dictionaries, at least we haven't found one).
Huguete - I don't think the lack of SD card support has affected Android's consumer adoption much; certainly adding them might make some more advanced apps possible, but the number of apps on iPhone that are larger than 10 or 20 MB is actually pretty tiny; even most Chinese dictionaries fall in the < 50 MB range, which would allow you to comfortably install two or three of them on a Nexus One. In Pleco's case, we already download most of our data files with our own system on iPhone so having the size of our application bundle limited wouldn't really affect us at all - we can store data files on an SD card regardless.
westmeadboy - I actually moved that post over from the iPhone forum since it seemed more Android-related, though I suppose it is a new feature discussion just as much as it's an Android post, and my comment above was answering the feature part more than the Android port - Pampuk, you're more than welcome to re-post it in iPhone and/or edit it to remove the iPhone suggestions / re-post them in a different post in iPhone if you like.
Relevance-wise, the tradeoffs do indeed seem relevant though I don't want to hijack the thread even more than I've already done with those... here's an Android-specific question: I was looking through the Android app catalog referenced in your recent Chinese-Forums post and I'm rather surprised the state of Chinese dictionaries on Android is still so poor; iPhone had far more / better ones at this point in App Store's evolution, and the ratio of iPhone to Android Chinese dictionaries vastly exceeds the ratio of iPhone to Android apps in general.
To use a horror movie cliche, the Android Chinese dictionary market isn't just "quiet," it's "a little too quiet" - it could be that there's a great opportunity there that nobody's taking advantage of, or it could just as easily be that that there's some very good reason why nobody wants to write a Chinese dictionary for Android (or why so many people want to do it on iPhone). Can you think of any good explanation for that? Have you encountered any limitations in developing your own Android Chinese dictionary that you can see acting as a roadblock for a lot of developers? (limitations that perhaps Pleco might be able to work around with enough effort, thereby enabling ourselves to charge a hefty premium over other apps that don't)
Couple of things come to mind:
- Apple makes it much easier for international developers to create / sell apps, currently impossible in Android Market in many regions
- Installation of non-approved apps is much harder on iPhone, on Android everybody sells their awesome Chinese dictionaries outside of Android Market and focuses mainly on 2-RMB-per-copy-paying Chinese users
- iPhone has built-in Chinese handwriting recognition in all markets and a slightly less pathetic default Chinese font than Droid Sans Fallback, so the results for a similar investment of time are more rewarding
- Memory constraints / lack of SD card support on Android, though as I said above most iPhone Chinese dictionary apps are pretty small so that doesn't seem likely to be a big factor
- Some sort of performance limitation on Android I'm not aware of (slow Chinese font rendering, say?) that makes it much harder to develop a high-quality Chinese dictionary
