Perhaps the most curious details in the EEC filing are the OS references, with macOS 10.13 [...]. It's conceivable Apple could refresh its Mac line before macOS Mojave is ready [...]
I have had exactly that very same idea in my mind this last week: If new MacBooks are released at the "back to school" event, would I want to buy one running the first release of 10.14? These years I usually wait until summer before updating MacOS, so that I get the same rock-solid quality that I was used to in the past. If the filings say 10.13, that's
very good, for two reasons: First,
release of new Macs would be imminent (September at the latest). Second,
it's going to be possible to hold updating to Mojave until they polish it.
But, said that, it's still unclear if Apple is going to be able to beat the display/weight ratio that LG is offering with the 15inch Gram, and Acer with the Swift 5 (15.6inch at 1kg, which has no Apple equivalent in this moment: The MacBook is 12inch at 1kg, the MBA is 13.3inch at 1.3kg, and the MBP is 15inch at 1.8kg).
For replacing my 13.3inch MBA, I want a better display/weight ratio: I want both a bigger display, and a lighter weight. If Apple cannot achieve it, it will be the first time that Acer and LG beat Apple in the design area.
I really don't understand the "cheap MBA" fever. I don't want cheap. I want big screen, low weight. Price doesn't matter, because I'll make it last.
