I was thinking about one of those super low profile usb flash drives like:
https://www.amazon.com/SanDisk-Cruzer-Low-Profile-Drive-SDCZ33-016G-B35/dp/B005FYNSZA
That is small enough that it won't get bumped and broken easily and you
would have to go out of your way to pull it out of the system since
there isn't much to grab hold of.
As for speed, the amount of data that is coming off of the USB drive is
minimal, so even if it was a little slow it wouldn't really slow down
the boot process much.
Besides, who cares about the boot time. The real bonus will be programs
starting instantly once you are up and running on and NVMe.

Knowing my luck I'd lose that USB drive (I assume you mean a thumb
drive, not a USB connected spinner). Am I correct that /boot on the
thumb drive would slow the boot process, but everything after early
boot would take place at NVMe speed? I'm not particularly choosy about
boot speed. Go make a cup of tea.

You can always get a physically very small USB drive and put /boot
and the boot block on that. Then everything else can go on the NVMe.

Maybe you can get a rip-roaring machine, but how so if that post
2005 computer can't boot of NVMe? What do you do, take the UEFI
info and the /boot off another drive, and use the NVMe for / ? Or
do you boot off another drive, and then carve up the (assumedly
small) NVMe into /usr, /lib, /run ? Life gets a lot more
complicated if the machine can't boot the NVMe.

well, the beauty about the "add-in" cards is that you can use any
PCI-e slot on just about any desktop that is newer than vintage
2005. YYou will end up with a rip-roaring fast machine. :)

1 - yes and no. Yes, you can replace, but no, you (almost
certainly) need to get a PCIe card which converts PCIe on the
motherboard to NVMe on the ssd. We have one of those at work, not
too expensive as I recall.
2 - You should be able to. Don't know if that's implemented or
not.
3 - /dev/nvme0n1 as an example. So, for SATA, its /dev/sd<x> for
nvme, you get a /dev/nvme0 and then you get /dev/nvme0n1 for the
actual drive, as I remember. I don't remember what the partitions
turn up as, but I THINK they were /dev/nvme0n1p1 or something like
that. A second NVMe drive would be /dev/nvme0n2 I think.
4 - it should. Now, you MIGHT need some updated stuff, for
example smartctl may or may not work with NVMe on your distro.
And you'll probably need to download the nvme tool that gives you
control sort of like hdparm. Using an 'old' distribution might
be a problem (for some value of 'old')

For me, I would get a system that can use a NVMe. They are about
the same price as an SSD, but make and SSD look extremely slow.
This is the first I've heard of NVMe. I just read
https://en.wikipedia.org/wiki/NVM_Express , and now have some
questions:
1) Can I replace the spinning platter 2.5" hard disk in my 5 year
old laptop with an NVMe device? My research tells me an NVMe must
plug into a PCIe slot rather than a SATA slot.
2) Do you fstrim NVMe-hosted partitions the same way you do for
SSD?
3) When you install an NVMe card in a PCIe slot, what device name
shows up? Is it sd-whatever, or something else?
4) If my desktop has a free PCIe slot, does that mean I can plug
in an NVIe drive and use it?
Thanks,
