re: MacBook or MacBook Air or MacBook Pro

I travel for work too, use a gaggle of unique programs and hook up to a multiple monitor set-up at my desk. I use a MacBook Air... from 2011. After a battery replacement earlier this year it runs like it did when new.

Any of the 3 will be plenty for your needs. The little MacBook would be my choice. That said I'm waiting for the new computers to arrive in October, whatever they may be called.
