I had a MB Pro 2015, which I swapped for a 12" MB 2017 about 6 months ago. Wife is using a 2011 MBA, and I was waiting for this launch to see what they had to offer. She would definitely [like me] prefer the lighter weight, and the smaller footprint of the 12" MB over the new MBA, but it's now a fairly old model. So, buy now? Or wait? When is the likely update to the 12" models likely? If they are not likely to launch new models for even 6 months, I'll order a 12 for her. Don't want to order one now, and see a new model within a month or two.
