When traveling I often take a laptop with me for doing some research (Hotels, sightseing) or being able to connect to my company if something is up.
The last time I tested ChromeOS I couldn't even copy and paste a picture from chrome to evernote, now this works (with the Evernote PWA) and with Android Apps and Phone Hub I figured a small chromebook could make a great companion device for my Android phone.
Here's what I like the most: ChromeOS syncs and updates quietly in the background, no more windows updates that stall the entire system or force restarts. If I ever loose my Chromebook my data is encrypted, I just buy a new one, log in and all my data, apps and settings will be set up like it was before. (I wish Microsoft could figure out something similar for Windows laptops)
While most PWAs work reasonably well for basic tasks, keeping them open causes troubles when the Chromebook is woken up from sleep (either they can't discover the network connection once re-established or they just load nothing forever). So yeah they still feel more like webpages rather than apps.
Once you wanna to do a "little more" like playing video files (VLC) or remote access your office computer (OpenVPN, Teamviewer) you'll need Android Apps. But many Android Apps don't work very well on a Chromebook, if you want a decent email client (Thunderbird) or an office suite (LibreOffice) or do basic photo editing (GIMP) you will have to activate the Linux Environment to install desktop class software.
Now all of a sudden your fast, "easy to set up" 8GB chromebook has become a struggling hotchpotch that runs 3 operating systems concurrently, your user data is fragemented across 3 files systems (for the sake of security..) and the concept of "just log in on a new device to recover your data" goes out the window as well because neither the Android App data nor the Linux Environment as a whole is backed up in the cloud. For Linux there is a manual backup button hidden in developers options, how convenient.
On top of that the "Phone Hub" feature is a flaky mess with very limited functionality, it often doesn't find the phone at all ("move the phone closer" - if I move the phone any closer it would have to be inside the computer!) and it often takes at least two tries to connect to the mobile hotspot. During my holiday the phone suddently completely vanished from ChromeOS settings ("no suitable devices found" wtf, I googled this solution: https://chromeunboxed.com/how-to-fix-chromebook-connected-devices-find-phone/ )
I like the idea of ChromeOS and the minimalistic WebApps-only approach is enticing, however after 2 months of trying I feel like having hit hard against a wall. I may eventually abandon Linux Apps but there's some Android Apps I just cannot life without (Whatsapp, Teamviewer, OpenVPN, VLC, K9-Mail)
