Just bought the "Scratch Adventures" book. In Mobi, it was hard to read on the kindle DX. Could not scale it with the usual text scaling command.
Downloaded PDF, and it was perfectly readable even with middle aged eyes and bifocals.
What's lost ? The time downlaoding experimenting to see which format is readable on the device.
Is there a way to scale the display of O'Reilly .mobi books on Kindle DX that I'm missing ?
Unfortunately it appears that the mobi file for this file will only work on certain devices. You can find this information on Amazon here: http://www.amazon.com/Scratch-Program... if you clink on the check mark next to "Available only on these devices".
O'Reilly does have a 100% satisfaction guarantee, and more details on this can be found here: http://shop.oreilly.com/category/cust.... I do apologize for any inconvenience this may have caused.
