Most of the time the cpu in my laptop is idle waiting for me to type
the next key.  Doing this faster does not give me anything visibly
faster or better.  It is still idle waiting for me to press another
key.  I am not bitcoin mining on it.  The only stress is playing
videos which it does fine.

Small nit: Actually Moore's Law says that the number of transisters
doubles.  This increase in hardware density does usually produce more
performance.  But it isn't quite the same.

Note that the original poster's machine was only a few years old, much
newer than my machine.  He posted that he had an i5 with 4G ram with
1G nvidia graphics.  That puts my older Core 2 Duo to shame.  And yet
even with his much newer hardware, well within your newer hardware
limits, he was still complaining about lack of memory problems.  What
say you to that?

I didn't buy my machine a decade ago.  More like five years ago.  The
biggest benefit was that I replaced my T43p IDE drive with a much
bigger and faster SATA SSD in the T60p.  Plus the T43 always ran hot.
The T42 was a much better machine.

I guess relatively speaking I both am a hard user of equipment and
also I take care of my equipment such that five years using a laptop
seems like the blink of an eye.  I am still using it and it is still
going strong.

But really I have been eyeing the lower power cpus and lighter weight
laptops with envy.  The problem for me is that they all have low
resolution displays as compared to my T60p.  I am sure if I spent
*enough* money I could buy a better display.  I keep waiting thinking
that eventually resolutions will increase again.  But can I get a
better display and also get a good keyboard at the same time?  That
has been a challenge.

Plus I hate to spend the money on a new machine that won't be as good
as the previous machine.  By as good I can list all of the important
items to me.  For all of those on my list a new machine wouldn't be
better for me.  Mostly because the display isn't better.

The only two items that I see so far that a newer machine would be
better for me would be better battery life and lighter weight.  I can
only get almost four hours now.  I eye some of the 12 hour ARM laptops
with envy.  But their keyboards are not as nice as my ThinkPad.  And
for the ones I have looked at I am not joyous about their more
restrictive hardware.

Yes!  Most definitely.  That is one of the best things.  The ability
to remove bloat.  Running a lean and efficient system is one of the
best things.

However note that he original poster in this thread was complaining
that his 4G ram machine wasn't large enough.  I still think 4G of ram
is quite a lot.  Or at least it should be.  It is still sufficient for
me.  If Debian at this time can't fit in 4G then that is bad.  And I
said why because there are many smaller ARM machines and I think they
are the future.  But I think the problem is most likely heavy desktops
and heavy web browsers.  Those are the traditional biggest bloat items
on today's systems.

I think they look interesting.  I don't have any experience with
them.  I don't know if that is a "yet" or not.

I have been maintaining that the best thing about the Raspberry Pi is
that it forced the price of these types of systems down into the
affordable range.  The Raspberry Pi isn't a great system.  But it has
created a good market for much better systems.  That's great!
