First, there's nothing "toy: about Swift. It's a full featured language on par with Rust, Go, etc.
Second, whether some random web dev or embedded C dev or Java dev wants Swift or not is irrelevant to its intended audience and utility. It's not for "professional developers" in general, it's for Mac/iOS application developers, and thus, for Mac/iOS users (that benefit as a side-effect from developers having a modern/better language to implement stuff).
>I'm buying a powerful laptop, I don't want cloud storage.
So? Millions of users do want it, judging from the huge popularity of Dropbox, Google Drive, MS implementation of the same, etc.
>I want the possibility to dual boot or share drives with other operating systems, I don't need a new proprietary filesystem.
Again, irrelevant. Lots of Mac users, and tons of pundits HAVE asked for a "new proprietary filesystem" to replace HFS+ and Apple obliged.
And whether you can "dual boot" or "share drives" is orthogonal to whatever OS X has a new native filesystem. You can still format the rest of the hard disk on another fs to dual boot, and you can still share drives with other systems in NTFS, xFAT, etc.
>I don't want compressed memory, I want 32GB of RAM.
And I want a pony unicorn. But until Intel delivers boards that accept 32GB low-power RAM of the kind that goes into Apple laptops, we're not gonna get it. And Intel gives late 2017 / early 2018 as the date for those. (Existing PC laptops with 32 GB ram merely sacrifice battery life using regular high power drawing RAM -- and even those are far and few between).
(And of course compressed memory helps whether you have 16 or eventually 32GB of ram)
>In short, Apple is spending a lot of effort making features that I, as a professional developer and 20 year Mac user, don't want.
Well, as a 15 year Mac user and 20 years professional developer, I do want those things.
I don't particularly care for the touch strip though -- I'd prefer it to be OLED physical buttons giving both tactile feel AND changeable inscriptions.
