Passwords sync just fine between Macs or PCs if you use Apple or Microsoft's complementary services (or something like 1Password). iCloud Keychain for example makes this just as seamless.
> A new Mac or PC costs you at least and hour of downloading apps and getting things up and running. And then you forgot something
Most of the time though all they did was use the web version or give up. But apparently that's better than "an hour of downloading apps and getting things up and running". There's also plenty of ways to automate that, or just restore it from a backup.
Granted, not as fast as just using the web versions of everything but then again, I can do that on my Mac or PC just fine too, without any additional setup time.

A whole lot of things.

This works with any OS that has a Guest mode. Both Windows and OS X do this, and just about any Linux distribution can be set up in the same way. Without (re)booting, requiring an internet connection or a Google account.
But the title of this article is why the author left behind the Mac and the reasons for that are extremely shallow. Most of the time they don't even go into what makes it better than a Mac, that was mentioned maybe twice and honestly not for great reasons. A one time setup cost isn't exactly a great reason either.
The rest is just "look at this shiny that has more than enough oumpf for most users". Which is totally fine, new and shiny is awesome to write about and having a great experience with it that makes your realise you can change some aspect of how you work, improve your productivity and not pay Apple's hardware prices is great. But then just write that.
Now you can have a finely tuned native Linux OS that's designed for Chromebooks. You can always dual boot it with ChromeOS to solve the problem of guests using it.
I actually just ordered a Chromebook yesterday. Can't wait until it arrives this week and set it up with Gallium.
There are 101 (really) Chromebook models, past and present. 33 are ARM, but GalliumOS supports almost all of the remaining 68.
The main issue with desktop Linux on ARM Chromebooks (that I encountered) is HW acceleration. GLES support is sketchy to nonexistent among the current crop of window managers. I am hopeful that some of the work the Pyra team is doing to bring a standard accelerated desktop to a mobile device can be reused on the Chromebook - I've already had some success with GLshim, which was developed for the Pandora.

A) Microsoft's windows business will go away quicker than we think.. Which is why I never hear them talking about it anymore. Nadella seems to be embracing the cloud as their new platform.
B) Intel is in a lot of trouble if ARM chromebooks catch on.
Trying to do presentations on a Nix machine is a nightmare.
In contrast, on Windows/Mac side of things - desktop keyboard is already bad enough with bottom row cluttered with win(command) repeated twice, plus menu/right-click key (why does this thing even exist?); On laptop, it gets even worse by adding add "fn" and often pgup/pgdn and other clutter to the mix. Then there's question of order in which they all come - is it fn, then ctrl, or other way around? was that alt beside spacebar, or is that win? etc...
- Full / 105-key layout, which is a copy of Windows 105-key layout with renamed and re-shuffled lower row, featuring: control, option(alt), command(win), space, command, option, control; 
- Compact (laptop / magic), where lower row has: fn, control, option(alt), command(win), space, command option; 
Other (Windows) layouts of the bottom row:
- Full/Desktop 105-key: Ctrl, Win, Alt, Space, Alt, Win, Menu, Ctrl;
- Lenovo laptop: Fn, Ctrl, Win, Alt, Space, Alt, Win. Ctlr; 
- Dell laptop: Ctrl, Fn, Win, Alt, Space, Alt, Ctrl. 
Now, this is ridiculous.
So my point is: sure, there are (ad-hoc) standards, but way too many of them, and all of them try to pack too many keys around core QWERTY field, especially lower row. Chromebook is the first one on record to prune this and offer a clean, usable layout.
 On some models, PrintScreen takes place of second Win key
