Unless I have to do some serious video editing, for that the 2011 MBP is still better, but for most other things this will be the main one. Well pleased with it.

That's something I've been guilty of with the 2011 MBA. It barely dets 2.5 hrs on a charge yet the battery condition is reported as normal.

Now I have to check my car door for damage after a stupid old trout dinged it while getting out of her car. Moronic bitch. If there's any damage I just might inflict some to hers in revenge. Getting the key ready…….

Not Cupertino but somewhere in one of the Australian Apple Stores.

From what I hear, the battery swap isn't much more complicated than your description.

The reseller I bought it from has had a deal with Apple for the last 10 years or so where they buy in MacBook Airs after Apple has used them for 2 years. It's a sweet deal.

Yep, that's the one.

@skematica I had a "battery needs servicing" warning on my 2008 MacBook Pro when it was running Mountain Lion, Mavrix & Yosemite. But when I updated ot to El Crapitan after fitting a fast SSD in place of the HDD, the warning vanished, never to be seen again.

The first thing to try is turn it off & back on again. If that doesn't work, download & run the latest Combo Updater for your OS.

Got it. The ex-Apple 11-inch 2014 MacBook Air, that is. Very nice, comes with Yosemite, so I'll have to update it to El Capitan before using Migration Assistant to shift the stuff from the current MacBook Air. I'm proposing to shift the stuff from a Time Machine backup rather than from the Mac itself, I know of a few horror stories when the latter is attempted.
