Yeah, like others I take mine on vacation or for (sometimes up to 3 month) business trips. I was really happy the first extended trips I took without my laptop, not carrying a MBP around on my shoulder was liberating (and better for my posture) ;-)
For vacation I only take the iPad, but for those long business trips I take and leave my MBP at work and keep my iPad at the apartment. I think it's healthy to define / separate work and personal time while working abroad and the iPad helps me define that routine, believe it or not.
