This morning I downloaded this app via the app store. After the app had installed, it wanted to install some rosetta software and restart. THEN the problems started! All of a sudden, I couldn't get online, iwork wouldn't launch, nor would sony's eBook. I tunes wouldn't pull up the store! I then began to delete this app using cleanapp, found several additional files on my own and started to secure delete. Slowly the problems went away. During secure delete, iwork wouldn't launch unless I stopped secure delete. THIS WAS ODD! I will let Sony and Best Buy know about this crap!
