storage wise i would love 512 but 256 is more than enough
No worries on the post, mostly I mention it so you can find more information beyond what may be discussed in this thread.
Only you can really decide if the convenience of the extra storage is worth the additional cost.
In my case I had a 256GB Air and it got a little cramped at times. Nothing I couldn't work around, but enough to be annoying at times. So when I bought my rMB I opted for the 512GB version and couldn't be happier.
Sure, a lot of your stuff is in the cloud -- but it's still quite helpful to have locally synced copies for times when connectivity is limited or unavailable. If you reasonably think you'll find it convenient enough to justify the price, then get it since you cannot expand the capacity later without replacing the machine.
So I'd say that's worth about the same cash even though you get half the storage.
I'll beg to disagree; I don't think you can reasonable contrast different storage configurations. You either need the storage or you don't. Getting less storage than you need is false economy just as it buying more storage than you need. (to deflect the pedants, I'm using "need" loosely to incorporate varying degrees of convenience dependent on the individual)
If you're comparing the 2016 with the base 1.1 2015 model, the above will still apply
I was quite explicit in what I was referencing, and thank you, I'm
quite familiar with the specification differences. You didn't answer my question though. Let me restate it in a different way. To what extent do you think web browsing, working with word docs, or using an rdp client is in any substantive way cpu bound, gpu bound, or ram-speed bound?
As for battery life, the 10% extra is helpful only if if you need to run on battery into the sweet spot that is beyond the 2015 model's battery life yet still within the 2016's battery life. If you need is less or more than that sweet spot it matters not.
I ignored the 512GB unit as the OP hadn't mentioned any need for the extra storage. There's no value in having a 512GB SSD if you'd never even get close to filling 256GB. With the new info from the OP, I've now addressed that above.
