Yes, whoever can shrink this down to the size of something that would fit in your pocket would make a killing. Imagine not only being able to make phone calls, but use productivity software and even browse the internet.
The request said 'shrink it down,' it didn't also say, 'neuter it to 3 gigs of RAM and cut CPU and GPU performance to a small percentage of what it was such that many modern websites won't function.'
The T480 as a daily driver, while slow by current standards, would still meet the needs of many. I use mine often and with plenty of RAM and storage it's still very capable, if underpowered for some tasks.
Incessantly trying to make the Librem 5 happen, as if it's the answer to everyone's needs without a shred of practical reasoning, just makes the project look like a silly novelty.
Yes, shrinking things down has it's own costs and tradeoffs, what a surprise. Some people may find such tradeoffs suitable, in case the main features are still there. I do in this case.
Then actually state the specific costs and disadvantages when you respond if you have even a shred of interest in contributing anything remotely informative, so you're actually adding to the discussion versus consistently adding little more than noise.
Otherwise, you're just conducting a years-long, nearly endless amount of low-effort, shallow shilling of a commercial product here, as if it's the simple and pat answer to nearly every question asked, no matter how tangential or unviable, or more charitably, how particular a use case it serves.
Someone could complain about their 60 mile commute by car, and you'd say, "I really enjoy walking two blocks to work, you should buy these shoes," add nothing more, and then move on to do it to others several more times that day.
In a way it would almost be sad if you aren't getting paid by them to do this, because it's all so incredibly...measly.
Nope they just called it a smartphone when you could hook it up to your laptop and connect the phone by infrared, USB, or later Bluetooth when it appeared. Using the phone manufacturers software that was naturally free for Windows 98 but also W2K, XP and even Mac sometimes.
You really want the headphones when you're using the laptop as a phone because it can have audio feedback otherwise, especially if using the built-in laptop mic.
iPhones just weren't that smart when they finally arose, you did have to use your imagination but it wouldn't get you far in actual computer interaction like smartpones are supposed to, compared to a Motorola or Sony-Ericsson true smartphone.
You can only imagine how much better it would have been if more choices would have maintained their leadership and there were still other options besides only the relatively shoddy Android and iOS.
