It finally occured to me, after all these years, that I could read a chess book 'on the computer.'  Take Dvoretsky's Endgame Manual, for example.  I have the book and the CB version that came out at the same time.  So (after all these years!) I finally realized that I could read the book while making all the moves on the ChessBase screen, saving time in setting up positions, etc.

Beyond the obvious - looking at variations in my head before playing them out on the screen - is there any downside to this method?  I know that one good way to increase board sight is to 'memorize' board positions in print diagrams and set them up on a board for solving, and I still intend to do this by solving studies and positions (from Imagination in Chess, for example) with a clock and time limit.  But is there any downside to doing more studying on the computer screen?
