Not really. Both are comparable, depending on what your particular use pattern is. If you need a laptop, the Surface 3 competes with the MBA; if you need a tablet, it competes with the iPad Air. In my opinion, in both of those use cases the Surface compares quite unfavorably (size, weight, battery life, power, etc). BUT, if you need both, then the Surface Pro 3 starts to shine, and clearly beats the iPad Air + MacBook Air combo all over the place.
So, again, it all depends on what you are looking for.
In my opinion, the whole issue is somewhat moot unless this is your first and only computing device. If you love Windows 8 and/or have to run Windows programs, you have no choice, and the hardware comparisons just don't matter at all. Likewise if you love OS X or iOS and/or have an investment in software for those, you have no real choice, and the hardware comparisons just don't matter at all. If this is your first purchase of many, it is the entire ecosystem that you are buying into, and that is more important than the specific hardware of this one device.
Which is, of course, the main problem with this thread. Microsoft has put together a pretty nice set of hardware to work with their software. Too many of us on this board, though, are wedded to Windows or OS X/iOS to really give the hardware of the Surface Pro 2 a decent evaluation. Personally, I see a lot of nice ideas I'd like to see Apple bringing in to one line or the other (but really never have a need for a tablet which changes into a laptop of vice versa so don't want the severe compromises associated with that).
