I'm not even interested so much on laptop keyboards. I always work on my desktop setup with an external keyboard.

It's really hard to get an external keyboard with a track point. For laptops there are a lot of models to chose from, both used and new.

I didn't say corporations can't have an ugly laptop lineup.

I'm saying that the trend of consumer/business laptop lineups is to make all of them look similar to a MacBook, because that's what most people want. Of course there will always be exceptions, like the ThinkPad.
