There was nothing in 2025 laptops that I would have replaced it for, the use cases haven't changed from my 2009 requirements in computing on the go with a cheap laptop like device.
Its replacement is now Samsung tablet with DEX capabilities, which I will likewise use until it dies.
LD, average distance between Earth and Moon = 384,399,000 m [1]
C = circumference of moon = 10,917,000 m
R := approximate round trip distance = 2LD + 0.5*C = 774,256,500 m
n = total number of thinkpads on earth <= total number of thinkpads ever manufactured = 250 million [2][2a][2b]
W = width of thinkpad = 0.3366 m [3]
T = total thinkpad distance = n * W <= 84,150,000 m
Alas, T / R, the ratio of total thinkpad distance T to our lunar round trip distance R, is at most about 0.11 .This is with the optimistic assumption that the total number of thinkpads on earth equals the total number of thinkpads ever manufactured. A more conservative estimate might be something like n = total number of thinkpads manufactured each year * mean lifespan of a thinkpad = (12 million thinkpads / year) * (5 years lifespan) = 60 million thinkpads in good working order for a lunar round trip.

[2] IBM sold 25m thinkpads before selling product line to Lenovo. By 2022, Lenovo had sold 200m thinkpads. With linear extrapolation to 2024 that gives approx 250 million thinkpads manufactured.

Sometimes having one software would be fine like iptables? Anyways, i was pretty fed up with not being able to do much and networking being this bad, then it come in first half 2024 an update that they forced 2FA on my account even tho i didnt wanted any of it, i logged in had to set it up and forgot to disable it back because i Dont want 2fa, i just wanna you let me manage my own security please. A month later i lost access to my phone which had the 2fa app(dont buy chinese phones, they die too early, motherboard died in it and i dont have money to recover from such state), i asked the customer support if theres some way to reset it and get back in well there is just i need to go throught some software which was legal age by now, and navigate it with vague instructions, after 2 days of calling them and trying to do it i gave up
If you still wanna learn working with servers, networking etc. i recommend just getting your own server or choosing some other provider, NAT is not an excuse, cloudlfare tunnel helps you out,
