My laptop now > 10 years old now runs Ubuntu.
At least everything works, put a Huawei 4 G stick in it and internet all over Europe.
This Raspberry has the Huawei 4 G stick in it now so I am online in a flash with one click
and offline after that with one click so no hacking and a dynamic IP address to make hacking even more problematic.
Did you have a P4 before the Pi5? If so what's the main difference in experience?
I was tempted by an N100 based toy PC at Xmas but managed to resist.
Yea, we will see were it goes...
My 20 year old PC upstairs still runs xfree and the old audio system (before Alsa), and works still perfectly with my satellite stuff.
Is an AMD 486.

Considering how important a computer is to our professional and
personal lives, why do people go to great effort to save a few
dollars?
If a cheap PC fails, it will take days of your time, or more likely
weeks, to recover.
If an expensive one fails, it takes just a much.

I had an original Raspberry Pi way back with composite video out but
never really found something it could do well enough to be interesting.
I found cheaper STM32 development boards more to my liking. YMMV
The Pi5 is quite a big step up from there! Even came with working GCC >compiler configured in the standard distribution which was nice.

N100 looks quite capable. My only concern is the whiny fans on these
very small enclosures. Fan noise increases rapidly with rpm and tiny
fans don't move much air. SFF is as small as I like to go.

FWIW, my *nix Desktops consist of cheap, refurbished, small form PCs,
stuffed with SSDs.
The STM GPIO interface typically provides a digital interface to my electronic circuits. BSD RPis are used as intrinsic IDE hosts while
Blue and Black Pills are accessed via a STLink.

Can it run LT Spice? I spend too much time running Spice.
My new big-box Windows machines, monster CPU and lots of ram and SSDs,
are disappointing because they only run sims about 2x as fast as my
old Win7 machines.

Presumably it fails less often. Cheap electrolytics, cheap fans,
under-cooled parts will fail.
I just bought four new identical tower PCs, for work, home, cabin, and
a spare. Once my main box was set up, we cloned the SS drives to the
other three. So if my work PC dies, I have three others available.
They have identical monitors too, so my desktop won't go crazy if the
video resolution changes. I hate when that happens.
I decided when I had to replace mine that an i5-12600 was about the peak of performance/price that was a significant improvement over the 3770. I don't like paying through the nose for the fastest possible CPUs.
We have sort of hit a point where CPU improvements especially for single threaded code have hit an insurmountable bottleneck. There is a sweet spot for
the amount of ram and fast disk.
If you put it onto a UPS and enable all go
faster options for the SSD cache write through (risking potential data loss if
power is ever lost) you may get some improvement. You would have to decide if the speed gain is worth it to you.
If you check LT Spice on various CPUs I think you will find it correlates closely with ram speed and single thread performance on CPU related benchmarks
(obviously with a bias towards floating point code).
If you are prepared to risk data loss then another option is using a RAID0 array of identical disks will get you another factor of 2 or 3 if the system is
mainly disk bandwidth limited (and it may be if extensive logging of data is occurring during a simulation).
Some of the best designed PCs are from the gaming community suppliers. If you remove the graphics card entirely the main CPU graphics system is more than good enough for all 2D design and some 3D rendering work.
They perform incredibly well and have huge slow fans so under ordinary heavy loads they remain very quiet. Ones intended for corporate office workers tend to have inadequate power supplies and small noisy fans reflecting their typical
workload and noisy environment.
Your choice but owning several machines of the same vintage leaves you exposed
to any glitches in the new machines or their OS's. MS has been known to brick portables on Win10/11 from time to time - not fun at all.

I haven't tried it on LT Spice but it seems to be able to run any
floating point code that will compile on it so I don't see why not. It
can also drive full QD displays natively at MPEG playback video speeds.
The main weakness as default built is that if you are careless about how
you use it you can run out of wear cycles on the sD holding the OS and
swap file! I know someone who did just that...

Most of us have way more compute power than we need. A pokey old
laptop will show a movie just fine. About the only compute-limited
things left are games and Spice.
Well, Spice is sort of a game too.
If you check LT Spice on various CPUs I think you will find it
correlates closely with ram speed and single thread performance on CPU
related benchmarks (obviously with a bias towards floating point code).
Enabling more cores doesn't help much. What does seriously help -
sometimes 20:1 - is relaxing some of the sim parameters. I do that
until something obviously breaks, then back off a little.
