the difference between a thinkpad T14 with replaceable RAM and SSD and a T14s with soldered RAM and SSD are minimal. depending on the specific generation and features, the T14s can be heavier than the T14.
i'd accept soldered RAM if it is at least 16GB, (though 32GB would be better) because i'd rarely need more than that. but a soldered SSD never. that holds my precious data, and even if i have a full backup, i do want to be able to take out the SSD when the laptop dies, or replace a broken or worn out SSD (as i had once). the risk of not being able to recover data from a soldered SSD is just not worth the few grams saved in weight.
The nice thing about picking up older laptops is that the upgraded models don't really hold as much extra value compared to what they cost new so if you keep looking you can get a pretty maxed out machine for not a lot more than the more common low-end ones.
a cloud backup for a 2TB disk is too expensive or to slow. an offline backup is not automatic and only current the moment i run it. a combination of both is more complex. an always synced full backup is difficult to achieve. it is possible when the only places where i use the laptop are at home and at the office. as soon as i add traveling and using expensive mobile data my backup becomes unreliable or to expensive to maintain or restore. in other words, even if i have a full backup, i can't always rely on it.
the data storage alone is not the issue. the cost of accessing that data is. not every place has unlimited fast internet that would allow you to download that much data without problems.
with a replaceable SSD i can (and in fact just did a few weeks ago) take the SSD from the old laptop and put it into the new one. took me 5 minutes.
restoring all that data from the cloud would have cost me a few hundred dollars in mobile data fees. or several weeks of visiting a restaurant which has free data, but would also have racked up a restaurant bill not to mention the time that would have been taken away from working.
With BackBlaze you can have them ship you your data on a hard drive. They charge you for the hard drive. But if you send the hard drive, they refund your money.
it's reliable in the sense that the data is there and won't get lost, and i can always access it to download bits and pieces if i need them. it is not reliable in the sense that i could always do a full restore from it without cost. having an unsoldered SSD reduces (but doesn't eliminate) the risk of me having to do a costly full restore from that backup.
I travel for work not as much as I use to. But a full day on and off planes with layovers can turn into 14 hour days.
And that 14 hours turns into 8 going back and forth between conference rooms with it powering a USB C portable monitor which is getting power and video from one USB C cord.
not the same person, but i don't. however my laptop for sure does because even when i am not working it is used as a communication and entertainment device. and when traveling those hours go by fast. unfortunately battery run time is one of the issues that linux hasn't cracked yet. i wish i could get 14 hours of battery time out of my laptop
