I have a 256 gig SSD and 1 TB HDD both internal. There is no benefit to the latest machines that would make up for losing my internal storage. 0.25" thinner so I can carry and extra box and cable? I also have 16 gig of ram which cost me $80 back in 2011. I am aware I can buy the upgrade from Apple for the lasted, but $300 just to break even with what I had 3.5 years ago?
This one isn't a dealbreaker, but I do use my ethernet port a few times a month. I'd buy a machine without one but I'd still miss it.
Apple just keeps taking away features and performance to make it thinner. If the machine this thread is about does turn out to be real, it will be 4 years newer than mine and still have a slower CPU and less features.
While I can understand where you are coming from, like for like - your machine as opposed to the 13" rMBP you could buy today is better in every way than the machine you have now, when you took delivery of it, i.e. before you modified it, and still is in most ways. The CPU and GPU is WAY better on the new machines. Not to mentiom USB and Thunderbolt revisions that your machine doesn't have and never can.
Don't compare an MBA to a MBP, that's not like for like.
Storage I get, but it seems you are using it as your only computer, so it has to serve dual purposes. Apple doesn't build laptops to replace the home computer with mass storage and to be your media hub. That's why they make iMacs
If you have your entire iTunes library and Photo collection (iPhoto or other) then I see your point completely.
My Mac mini server has been the media and storage hub of the house since we got it in 2010. I've also upgraded the storage and RAM on it, did the conversion to SSD, etc. it is going pretty strong. So I get that part. But don't try to say that today's machines aren't as good, they are simply way better in every measurable way (except storage capacity possibly in BTO configurations.) I would love to get a new Mac mini (if they ever update it!!) because it will be 10x the machine I have now.
