I can't say I fully understand the trend to almost-exclusive 16x9, either.
I've read that this is because of the influence of TVs: pretty much every LCD maker is setup to cut panels in this form factor, and there isn't enough demand to make computer makers change this.
A couple years ago I saw a Lenovo blog post about how they could consider making taller laptop screens if, say, they got $20K pre-orders, but even then it would've been very, very expensive for the clients, and I don't think the idea ever went anywhere.
