Also consider Chromebooks. You get the desktop version of Chrome (ie whatever extensions you want), windowed interface, runs Android apps, and via the rapidly maturing Crostini project you can also run Linux apps. Heck on Intel based Chromebooks you can run Steam and use Proton/SteamPlay to run Windows games (and other Windows apps).

The nicest thing about the Chromebooks is that the software is identical, but the hardware varies from $200 cheapo devices all the way up to almost $2,000. This means you are far more likely to find your own sweet spot of price, size, memory & cpu, storage etc.

Some also have LTE so can be used as an alternative to a phone.
