My complaint is not about $25. It is that the person selling the product charges iphone users only and at a rate that is out of balance with similar priced products. Look at this way, assume Koichi gives all PC users Textfugu for free; however, if an Apple user wants to use Textfugu they must pay $5000. I would agree programming for Apple has more expense, and yes he needs to make money, but should it be 1000% more than similar Japanese language products? Then lets go a step further and say you couldn’t even use Textfugu on your Apple after buying it. You still had to go back to your PC to download the lessons just to view it on your Apple. That is basically how I see the situation of using ANKI on iphone.
