The speed differnce would be too great for Tiger to make up. The strongest PDA chess program currently is HIARCS running on a Palm ARM (imo). PF2 is close, within 100 points (or closer) and Genius Xscale is within 75 (or closer) points of PF2. I think it would be fair to say that Hiarcs might be 150 points or so stronger than Genius on comparble ARM hardware. I believe this rating for Tiger on a Palm is fairly accurate (+- 50 points) http://web.telia.com/~u85924109/ssdf/nr046.htm Hiarcs on fast Palm ARM is probably 300-400 points or perhaps It is almost all due to speed of the hardware andthe program's ability to utilize the hard effectively. Tiger is not optimized for the ARM at all. A fast ARM Palm with a program properly optimized could be about 40x or more faster than a 42 Mhz Palm Dragonball. At the 2100 level , doubling of speed mightbe worth 75 points (as you go up the elo scale, I believe there is a decrease from the impact of doubling). With a factor of 32x speed increase (2^5), 75x5 =375 is within reason. These are all based on using all the programs and I may be off a bit with some of these elo differences estimates, but I'm am confident that I have identified correctly which ones are stronger relative to each other.
