I have to wait and see how Docker works on VMs before deciding. macOS will still be great for my hobbies(iOS programming, Photography), but I may need a x86 Linux machine(thanks MS for giving Linux Teams) for work. On the plus side, if I do need to use Linux for work it'll help create a better separation between work and home.
Got a tip for us?

Is it my imagination, or was there a version of Parallels that ran on the old PPCs?
A lot of developers are in the same boat. macOS is Linux with commercial software. Its a wait and see just now on how it'll run. I did build a ruby app and shove it up to arm and it was fine and then for compiled applications you can send them to a build server. AWS code build is setup for me to build on push to master and then run the test suite and report back, something like this would likely work well for you too and costs very little.
Yes, you can. Just create a jpg on an Intel based Mac or Linux machine and copy it over to an iOS or Android device. They'll be able to read/display it just fine.
Microsoft Virtual PC for Mac. It was not a good experience to say the least. However, in the demo of running iOS apps they did have a Parallels icon with the Windows logo on the dock.
There was a product called VirtualPC, a stand-alone company that Microsoft bought, back in the day. That product was a CPU emulator, not a virtualization application. To that end, the performance was beyond horrid.
Probably your imagination, Wikipedia says it was first released in 2006. Anything prior would've been emulation, not virtualization.
My question is if the bit-level format of a REAL, DOUBLE, etc as stored in a binary file will be the same. Will they follow the same IEEE formatting standards that are used on Intel hardware. I ran into this problem when moving from SunOS SPARC to Linux Intel. All binary data files had to be reformatted at the word level. I'm not talking about image files, but data files.
I don’t get all the concern. Aren’t there ARM versions of both Windows and Linux? This shouldn’t be an issue. Just apps will have to be recompiled.
It would make a lot of sense for them to use iOS's formatting. So just test your scenario using iOS. If you need certainty, invest $500 in a DTK.
I'm just lol at the early comments in this thread that Apple would never switch to ARM or it will take 10 years.
Yes there was, they stated there will be VM support, Parallels will still work, no more Bootcamp.
Not sure if this what what you are concerned about, but you should no issues moving the binary data. These days almost all architecture run multi-endian so can handle data from other systems. In particular, the Apple ARM run IOS little-endian like Intel, but is multi-endian.
But everyone concerned should want the WWDC sessions.

I don’t think they specifically statement Windows would be supported. But it did seem to be implied.
Microsoft Word, Microsoft Excel, Adobe Lightroom, and Adobe Photoshop are shown running on an ARM Mac during the latest Platforms State of the Union video, if I recall correctly. Microsoft and Adobe are not going to drop the ball this time like they did during the transition from PowerPC to Intel.
A lot of reasons for opening up a Windows VM is to run that one obscure application your fiancé department requires you to use to sign of a PO and it is x86 code that runs on a specific version of Windows. ARM Windows is not a replacement for full Windows.

They have a built in VM it seems and they suggested Docker works. Windows wasn't mentioned as far as I recall.

They showed this in the keynote, you can watch on Apple's homepage.
Endiannes, basic data type sizes and alignment are identical between x86-64 and ARM64. You can copy data structures over network between an Intel Mac and an iOS device without any serialization. This is what makes this transition possible. And it’s the reason why building the same app for ARM and x86 is trivial in most cases.

The Platforms State of the Union video is available to everyone who's got a paid Apple Dev account.
It mostly comes down to support by the guest OS at this point. In the Platforms State of the Union video it was mentioned that booting into a 3rd party OS will be possible. If Windows 10 on ARM supports Apple's new hardware driver-wise, there's no reason it won't run both virtualized and on bare metal.
I guess it would be technically possible to run Windows for ARM if Microsoft allows it and Apple / Parallels provide drivers. But most SW people want to run is not available on the ARM version.
Apple has clearly stated that Rosetta will NOT translate VM, so full windows would require some third party to do a huge work.
Why wouldn't it be available? Windows 10 on ARM runs all x86 apps through emulation. x64 apps won't run for now, but as ARM chips are getting more and more powerful, that's bound to change at some point, too!
Most apps people run these days are still x86, or at least support it. x64 only apps on Windows are actually quite rare. Modern games and certain Workstation apps come to mind.
