I highly recommend the 1password desktop/ios combo. Even with the new keychain options. Even if you have to pay a bit. It works so well, not just for passwords but with all sorts of personal/financial data secure, accessible storage
Non-media production is fine without the 16g of ram, but I highly suggest 8g for everyone else.
I was holding on to my 17" mbp, but after it was stolen I had to replace with the late 2013 15" retina. And I'm glad I did. Don't underestimate the zip of these PCI-e flash SSDs from Samsung...
I just picked up this exact same machine, in my opinion you are very unlikely to ever notice the CPU speed bump. Basically, I knew this speed bump was coming and bought mine as is anyway.
Until they upgrade the discrete GPU, no point waiting or sending it back, in my opinion. If you are...
that's an important distinction, the difference between the classic unibodies that ended mid-12 and the newer retina models, which have soldered ram (no upgrading after purchase), as well as more expensive battery upgrades (all top case assemblies) and difficult SSD upgrades.
They are beautiful...
I don't see the point of this, when you can use a secure password manager like 1password, it has encrypted wallet that you can use to autofill credit card information
As others have said, an Air with 4G ram (on only integral gpu) is never going to be a desktop replacement, unless you become a tidy, clean, minimal type of user.
You should use Activity Monitor to see where you are hitting roadblocks, on a per app/activity basis.
I run a MBPro, 17", with...
Yes, and Yes. I'm running an upgraded 2009 iMac as a general second family computer. For work, I used to upgrade my MacBook Pros every 2 years, selling them on, but I've stuck with my 2011 MBP17" as its a quad core with thunderbolt, no obvious need to move on.
Now, I've gone so far as to...
I used the original temp sensor, I've had no unusual fan behaviour.
I pulled the optical drive on mine, put a boot Samsung SSD in there, then replaced the original HD with a 3 terabyte bulk storage disk. Our 2009 iMac is zippy and doesn't feel its age at all.
The phone wants to be on one network, it will favour wi-fi unless you turn that off. It will go to cellular after wi-fi, it its not available or deselected. You can't segregate data traffic btw networks.
Use Apple photo streams as shared, off of the desktop, via iCloud. You don't need to...
You already have the external monitor, I would def. go for the MBP.
Air plus iMac is not as cost-effective as consolidating that spending on a powerful MBP, also, you'll have to spend no effort to keep your systems synced, you'll have one set of backups, one monitor on your desk, etc. And...

You'll have to find a AASP with access to the Global Parts Xchange who will sell you the part
