Maybe true today. And I think only maybe. I mean what does the Geo have that the Zoop doesn't, except for a more liberal algorithm? There's a rumor that the latest Zoop even has Gauge mode. IOW, I don't know that the Geo has more than he needs, as I think it offers just the same as the Zoop. It seems like they both have just what he would need, no more, no less.
Regardless, still true in a year? If the algorithm would probably make a difference a year from now, should he ignore that aspect of the purchasing decision?
I am glad I didn't buy a Zoop for my first computer. I would have wanted to replace it with something better (i.e. more liberal and non-proprietary in its algorithm) in less than a year. Instead, I bought an Atom, which is the Geo plus air integration, and I am still very happy with it.
