It has a *decent* interface, nothing spectacular, and it's missing many features. Like, why is it that I can't import CSV files? Shouldn't that be a pretty basic thing? Or what if I want pasted numbers to go across columns instead of across rows? The graphs do not make it easy for you to specify what data you want to go where, what is the independent and dependent variables, etc. All in all I'm very disappointed, and I've also wasted way too much of my time trying to get this thing to do what I want. For shame Apple, for shame...
