I think there have been three Lenovo Duets.
There might have been two “Duet 3” models or if the first duet is refered to as a ‘3’.
The ‘3’ is considered an 11in display which means it has a small, cramped, less functional keyboard.
The ‘5’ is considered an 13in display. While most 13in laptops have a smaller keyboard in the Chromebook flavor they are complete; the Duet 5, however, seems to be missing a few keys. But that’s not my only complaint.
While I do not have the latest Duet 3 I have a Duet. It’s from Quebec Canada so it has an international keyboard which means they jammed many more keys in an already small area. The “sleep” battery life is fantastic. The Keyboard feel is solid but that has more to do with the key technology. Except that it’s sluggish it’s not all that bad. The weight/heft is nice. Lastly while I like the formfactor there can be a problem with some apps that need more screen.
On the otherhand I also have a Duet 5. It has the next gen processor that the latest Duet 3 has. Maybe a little more RAM and DISK. They keyboard is larger but rather than some missing keys they removeded the forward key and replaced it with a screenshot key. Strange! I will add that there is some unwanted flex in the keyboard and while it’s not as solid as the Duet 3 if I were a better typist I might like it more.
One thing that seems to chap my ass is that ChromeOS, still, only supports Android 9 in the stable branch.
As a side note…
I also have a Lenovo P12 (Android 12 or 12L). It’s a speedy little machine. Since I only use a browser, VPN and terminal application… Android, or iOS, are passable. The biggest challenge is that neither provide a terminal app so I’m at the will of a third party not to steal my credentials. The trackpad is not supported in the terminal app that I’m using. The trackpad is sluggish and lacks the PC/Mac experience. And the keyboard double clicks … a lot. I miss the ESC key and in the location where it would be is a BACK button, as in ChromeOS back, but is not actually a BACK button. It returns the user to the home screen. Weird.
The P12 does not have an ESC key
One problem or caviet is that VPNs are quirky. ChromeOS has a very limited VPN solution. It’s so bad that maybe they were or are planning an enterprise or school solution. When I decided to use Android’s OpenVPN I realized that I have to consider issues like SplitDNS and only one VPN route/connection at a time. It’s not a total mess but it is quirky and requires that I think about it a bit differently.
By comparison to my current Pop_OS desktop it, ChromeOS, just works.
The Last thought as I’m here… ChromeOS and Android both support multiple users and an optional guest user.
