15.6 inches Chrome OS Laptop/Tablet/Smartphone (All-in-One) , which I envisioned , is a machine which is a cellular Laptop (which has the physical appearance of a foldable Laptop or a detachable Laptop ) or it can be a machine like a folding Smartphone ( which can unfold into a 15.6 inches Tablet ) that requires a cellular/data plan for voice calling , just like a traditional Smartphone .
1. The 15.6 inches Chrome OS Laptop/Tablet/Smartphone(All-in-One) which I envision is a cellular Laptop , is a machine with a SIM Card Slot that require a cellular/data plan for voice calling just like an Android Smartphone . They are 4G/4G LTE/5G Laptops , they are cellular Laptops that operate like Mobile Phones or Smartphones . They can make telephone calls or receive telephone calls , send sms , send emails , WhatsApp , WeChat , Snapchat , Facebook , Instagram , Telegram , Zoom , Skype , etc., just like a Mobile Phones . Since this machine behave like a Mobile Phone , we got to have a data plan , we got to have a cellular plan with a Telco in order to make telephone calls and receive telephone calls and to stay connected to the Internet at all times . With this machine , I envision that it enables us to stay connected to the Internet at all times without the dependency of a Smartphone , without the dependency of another device . With this machine , I envision that we don't have to buy or puchase a Smartphone . And best of all , we have a PC/Laptop , and a Tablet and a Smartphone built into one device , built into one machine to meet all our computer hardware needs . There is no need to carry 3 devices or 4 devices . We carry only 1 device . We only carry 1 item . WE ONLY CARRY 1 UNIT OF 15.6 INCHES CHROME OS LAPTOP/TABLET/SMARTPHONE (ALL-IN-ONE) . Anyway , it is many times better to carry this than to carry this .
2. Also on the money side , there are added cost for getting a cellular/data plan for a Smartphone and a cellular data plan for a 4G/5G Laptop ( cellular Laptop ) . Meaning we got to have 2 cellular/data plan , one cellular/data for having a Smartphone and another one cellular/data plan for having a 4G/5G Laptop ( cellular Laptop ) . But if we have a 15.6 inches Chrome OS Laptop/Tablet/Smartphone (All-in-One) , we only require one cellular/data plan for it . Anyway , just because we have a mobile-broadband-capable device , it does not mean that we are relying on 3G/4G/4G LTE/5G for 24 hours to access the Internet . Sometimes we rely on Wi-Fi ( e.g. Hotspots , Home Wireless Router , etc., etc. ) inside the 15.6 inches Chrome OS Laptop/Tablet/Smartphone (ALL-in-One) to access the Internet , especially when we go back home to our house after work using our Home Wireless Router , and this help to save cost .
3. With the 15.6 inches Chrome OS Laptop/Tablet/Smartphone (All-in-One) , we can access the Internet and do phone/voice calling at the same time , simultaneously , without having to carry an extra Phone/Smartphone , without having to buy/purchase an extra Phone/Smartphone .
4. There is no need to purchase a Smartphone in order to tether our Android Phone/Smartphone and share its Internet connection with the 15.6 inches Chrome OS Laptop/Tablet/Smartphone (All-in-One) because the 15.6 inches Chrome OS Laptop/Tablet/Smartphone (All-in-One) have a built-in 3G/4G/4G LTE/5G module that can do phone/voice calling and high-speed Internet access at the same time .
