Anyone using a 13” Laptop with MS?

Considering a Macbook Neo, but the 13” scares me a bit. I’m working on a 15” screen now.

Aging eyes - don’t wear glasses yet but quickly approaching it (or should be using them now…).

I want to make sure I have enough screen real estate to work on.

I can always use an extended monitor, but the point of the laptop is being mobile, so that’s not always the best option.

Of course, the 15” macbook air is like, double the cost and then some already…

And this would really just be a “surfing the web” and Music Notation machine - would keep it pretty light in terms of any 3rd party apps.
