That is great to hear. i hope you, the OP and others don't have any issues with the KB. Might still end up with a MBA but for now I ordered her a surface laptop 2, at least to try out and see if it works for her. This is our first non-Apple PC we buy in over 10 years.
I think the main concern for her is a loss of confidence in the product. While this KB fiasco is not affecting every user, it does appear to be somewhat widespread. I mean for Apple to come out and make an official statement about it, I would think it takes more than just a few units to be impacted. Also, being a work-laptop my wife can't afford a lot of downtime, and our local genius at the Apple store told me it's a 7-8 business day turn-around for KB replacements, at least here in Canada.
The other thing is, even with us being deep in Apple's eco-system, her work is O365-heavy so the OS choice may not be critical, in fact her workflow might be slightly better suited to a W10 environment. I'm not confident or hopeful that she'll love this surface notebook but we'll see. Bought it from Costco so it would be an easy return : )
