What is the most annoying thing about chromebooks?

What most annoys me is that I have a feeling that I don't have control over the thing when I'm using it.  It's all "prepackaged" and realy just a browser for the most part, and Android apps support is not very good.

Limited offline usage and heavy dependency on internet connection

I purchased a refurbished Chromebook several years ago to use when traveling because my other laptop is old and heavy and not practical for traveling.  I mostly used it for checking emails and browsing the Internet because I have a hard time doing those on my phone due to poor vision.  I like it for what I used it for, however, I was unaware when I purchased it that Chromebooks have an "expiration date".  After a certain number of years, it is no longer supported for updates, etc.  Had I known that, I probably wouldn't have purchased one, but it was fairly cheap, so I didn't get too upset about it.  I just think it sucks that after x number of years you really can't use it anymore and have to buy a new one if you want to use a Chromebook.

Chromebooks have come a long way since the early days - a Linux VM/container environment, Android apps, more capable web apps - but it would be nice if you could play AAA games other than something like Geforce NOW.

The main problem about chromebooks are chromebooks themselves. Limited usage and functionality, and useless without internet.

Google's manipulation of your searching, resulting in disinformation.

AUE date. So environmentally damaging. So much perfectly good hardware that is obsoleted by Google for no real good reason. If a Windows or Mac can go longer than 8 years with similar chipsets (at least for old Macs) so could a Chromebook.

I can't stand that fact that Chrome is a GIANT memory hog.

I hated having to be tied to WIFI for the one I had. And I wasn't about to pay for a cellular data plan for it. 

After your end of life date you can longer get auto updates from google.
