I wholeheartedly agree with the sentiment.
Maybe one day there be a standard file format for chess e-books so that customers, having paid for a book, will know it will be compatible with their favourite reader app. After all, the profits are made from the book, not the app.
I have started using Forward Chess few weeks ago and I really love this app for working on my chess books. So far I've purchased 8 books (half of them I had on paper but electronic version is so much better!). I am really happy that my favourite publisher - New In Chess - releases books for this app. However 2 other publishers I like a lot - Gambit and Batsford - don't.
Gambit has his own app - Chess Studio - but for me it's unusabe - chess board too small, board colors too aggressive for my eyes. Their latest version was released almost 1 year ago. I tried to write to both Gambit and Batsford but 10 days later still no answer.
What do you think?
