I would avoid the iPad Air. Apple cheaped out on it by only putting 1GB RAM into it. Completely ridiculous, especially when trying to cram 64-bit OS/apps onto it. Low memory app crashes are something you may have to deal with IME.
1 GB is not "lots of memory" for it. I'd say it's adequate, but I can use up the RAM on my iPhone 5s if I leave a lot of Safari tabs in memory.IOS isn't Android. 1GB is lots of memory for it. I have multiple apps loaded right now and still have a few hundred MB free.
Yeah, Surface Pro 2 really is a touchscreen Windows laptop. Not really in the same class as the the iPad Air or Nexus 10. Much more expensive, and uses way more storage. Also way, way heavier.

Well, for me it's pretty much what I don't want. I much prefer a 7-10" dedicated tablet and a 12-13" laptop.However, I can put this in a tablet usage model, hence why I chose it. It is good if you need all spectrum of ability of dedicated tablet to a dedicated laptop, (and I would say this again) without two separate devices or feeling the need you missed your laptop back home/work or wanting to quickly break out your computer (without the bulkiness handling of a laptop).
Also, the expenses is justified, as you mentioned, it is component wise and performance wise a laptop with combined features that most laptops do not have (namely that Cintiq like pen display).
At the moment I would say Galaxy Note 10.1 or the Galaxy Tab Pro 10.1.
