This is a great discussion going on here about the Lenovo Duet, because I'm thinking of replacing my Windows 8.1 netbook with the Duet and pair it with my new iPhone SE 2020 when full travel returns.
When you say "pair it", what specifically are you looking to do? Are you simply referring to owning an iPhone and the Duet, or something where you expect the devices to interact with each other?
What I need is like a long battery life, some media consumption with WIFI and productivity apps like Google Docs and Sheets when I need it and browsing sites like Facebook and Reddit with Chrome and a PDF reader and a Kindle app if that's available for the Duet? Also is it true the security update ends in June of 2028 for the Duet?
The Duet will definitely be able to do those things. There are PWAs (progressive web apps) and Chrome OS apps that provide those capabilities. Android apps are available as well for those use cases where it is helpful to have something locally installed or doesn't exist in a Chrome OS/PWA version.
Yes, June 2028 is the current end date for security updates. But that will most likely change in the future since Google is working to de-couple the Chrome browser in Chrome OS from the rest of the OS. The result will be a longer period of support.
Even if the date doesn't change, the Duet will continue to function safely after that date.
What sort of pitfalls should I be aware of with Chrome OS on the Duet as this is the first time I'm planning to own it. I'm already comfortable with Android OS as I run Bluestack on my Windows 10. The model of Duet I'm looking at is the 64Gb storage model. Basically I plan to replace both my 2nd gen Kindle Fire 7 and Windows 8.1 netbook with the Duet.
Thank you for your insights.
Since the Duet doesn't provide support for SD cards, I would strongly recommend getting the 128GB model. They are regularly on sale for only $30+ more than the 64GB model. And maybe, you may find the need to enable Linux support on it for true, full desktop-strength apps.
The Duet supports USI stylus, so you might consider budgeting for one.
You may find that you won't need as many apps as you had on other devices. Especially apps that simply present the website in a more suitable manner on a mobile device. For example, there really is no need to install the Facebook app when the website displays just fine on the device, has more functionality, and doesn't have any hidden processes running in the background.
Given your description of what you plan on using the Duet for, I think it'll be a great fit.
