I installed the new firmware.
It works great!
The pocketbook reading app works much better than before.
Especially, it handles PDF files very well (faster and smoother) even better than other apps such as beam reader, document-to-go, and office suite pro etc. And the dictionary function is great!
Overal app speed has also got faster than before. This is quite a good start.
Good job, PB. Lastly, please hurry up for the 2.2 upgrade
