mongrel - thanks! That's about as strong an endorsement as we could ask for...
Smoodo - I agree with you that as it's designed now Pleco really is better suited to use on a PDA, but document reading is definitely something we're putting front in center in the "real" desktop version; Wenlin's great for that, and in some areas like rare character support / etymological info we're probably never going to outdo them, but I think there's potential for us to add some new things to the experience. Better flashcard integration, for example; highlighting words you know or words you don't know, automatically searching a document for unknown words and adding them to a new flashcard list, refusing to give you a mouseover definition for words you already know, that sort of thing. Anyway, that stuff's going to take a while for us to develop, so that's why we're interested in releasing something ASAP so that people who really want a version of Pleco on their desktops can get one without having to wait too long.
gato - Wenlin does this too, I think Smoodo's point was that was a basic sort of feature that we don't offer now but would need to offer in order for the product to be useful on the desktop. But yes, Apple's version of Java does kind of suck, which seems like a rather dumb move on Apple's part; if you're the #2 or #3 OS platform then you should pretty much embrace any technology that lets programmers write something once and run it anywhere.
garysaville - thanks! We're hoping we can do a better job too, or at the very least shake up the market enough that it inspires everyone else to work harder to improve their own products.
