I already own a 2013 15" MacBook Pro, but I need something with more portability as I travel quite often, so I'm willing to sacrifice performance to get it. I'm looking at the 11" MBA vs the new MB. budget is $1350.
You haven't mentioned the most important thing. Is this new laptop replacing your MBP or in addition to it? If replacing it then get the MBA, if in addition then get the MB.
