I found that the usefulness of the polar alignment routine outweighs the importance of 3-star alignment, I'm happily using 3.35.
The only thing 3-star alignment accounts for is cone error. You can easily determine the presence of that and correct for it if necessary without the help of electronics.
Apart from the additional problems with 3-star alignments, both 2- and 3-star alignment seem to use algorithms that aren't entirely robust. Depending on the chosen/available alignment stars the pointing accuracy can vary substantially, even if you take great care with centring the stars in a reticle eyepiece.
Cheers
