2. not widely supported by the community (plugins and premade decks)
3. no automatic kana or pinyin generation
4. not multiplatform, I never know when I might need to use a windows machine, such as at work
Ad 1: Even if there were no ways to get around it, paying the price of a single lunch for an app that would probably make it to top 5 most used apps on people's computers hopefully isn't a big deal.
Ad 2: As of yesterday there were 265 pre-made decks available in the iFlash community library (accessible from inside the app). Also, it's easy to export / import most stuff. Plug-ins are too much "fiddling" for me personally.
Ad 3: With no 1-on-1 relationship for kanji readings or pinyin, I prefer manually entering those from scratch to correcting automatically generated errors. Better control and helps me remember, too.
Ad 4: Windows machines at work even have USB ports disabled... Installing a non-work app is a big no-no. Not using any other Windows machines anywhere.
Anyway, I'm not trying to get anyone to change and for the most part it's all down to personal preferences. In the end, it's just a tool and the contents of people's decks matter the most.
Having said that, I have been playing with iFlash on the iPhone for about a week, though, and it's amazing. I wish I had it when I was doing my kanji/hanzi studying...
