Grab a Pinebook. It's slow, but still faster than Raspberry Pi, and has two
GB ram rather than one.
For $89, you don't care that it's only a stop-gap before you can get a
better one once such CPUs become available. Also, its manufacture quality
is pretty nice compared to other cheap laptops I've seen.
Pinebook would be nice, if they actually would ship some day :-/
I would instead get a novena, an actually shipping ARM laptop and it is
apparently free firmware/hardware besides a blob for 3D graphics.
It also has an intergrated FPGA.
According to wikipedia:
"The pinebook cannot be run solely on free software now (December 2017),
and the linux kernel choice is limited to an old no longer supported
version (3.10) with binary blobs to support most of the hardware,
including the Mali graphics or any kind of 2D or 3D acceleration.
Work is underway to integrate support into mainline Linux kernel, but
the manufacturer of the CPU (Allwinner) is notorious for its lack of
interest in supporting Open Source."

You can install the intel-microcode package. AMD processors have a similar

It looks like the updated microcode with the latest fixes is currently in
Debian testing so I guess you could grab it from there directly and install
manually if required.

Has anyone revealed how this microcode avoids the Spectre problem?
Does it, for example, disable memory fetch from proteted memory?
The microcode is proprietary (non-free) code, so nobody knows if the
patch is better or worse than the bug...
So is the microcode embedded in your CPU, which in the case of intel
this is encrypted for god knows why.
The only CPU without microcode hardware code signing enforcement and the
documentation to theoretically make your own updates is POWER8+
Keep in mind that most CPU's have always had serious critical security
bugs without microcode updates so not applying them is a security risk.
