Hear, hear!  I've been dreaming specifically of Genius on a PDA since I got my
first Newton many moons ago.  (Actually, since the Newton is ARM based, maybe
Rebel or The King (ala. ChessMachine) would be more appropriate.  Too bad the
Newton is a dead platform.)

My results agree with this.  Heck, it even beats Deep Green on a 160Mhz Newton
at even time controls!  That's an 8:1 speed disadvantage!  So far it is also
2.5-0.5 against my Sapphire II at 2sec/move.

I'm just happy there is any PV at all.  :)  Besides, aren't most moves near the
tips mostly garbage anyway?  Also, you'd have to change batteries after it has
searched one position 14 plies.  :)

Me too.  Heck, maybe I'll buy a dozen copies just to encourage him.  Way to go,
Richard!!! :)   (Also, good release strategy:  get us hooked on having Genius in
our pocket then reveal the $99 registration fee...  ;)  But seriously, how long
before we get to register it?

Also, I was curious about permanent brain:  I found that it did make some moves
instantly; does it already have some form of permanent brain?  With some of the
larger memory models of the Palm available, do you think Richard is considering
the option of having hash tables?

Steve, do you know how long has ChessGenius for the Palm has been in the works?
I am surprised I haven't heard a whisper about it until now, when a playable
version is available.  Is there another person involved to do the Palm UI, or is
this entirely Richard's work?
