I too have been having a great time with the Evo especially with the apps I've downloaded which go way beyond the currently poor analysis option built in. I noticed in the last update as Andre has mentioned, Chessnut have increased the range of ELO for the built in SF16, it now has a max ELO setting of 3190. However, SF is still only taking a very small amount if thinking time. This is fine for mere mortals but no good to get accurate analysis for a game. I pitted Shredder mobile rated 2600 ELO against EVO SF16 set at 3190 and SF Evo was hammered! I gave Shredder 60 minutes for the whole game. I'm sure if I only gave Shredder mobile 1 second per move it would probably lose, but this is an indication that EVO SF16 is not actually playing at that level. In the game, EVO SF played black but ended up in a very poor position with several undeveloped pieces. Fun to play against but definitely not for analysing games.

However, with apps like DroidFish and PGNMaster, the EVO is a joy to use and being able to analyse all the moves in a game and save the results to a PGN file is great. This can be done from a tablet or smartphone of course, but having the attached board and piece recognition is more pleasurable than staring at a screen and making moves with a finger.
