I don't, sorry.  Based on my experience with other Thinkpads and looking
at the list of hardware that's inside, it *should* "just work".

According to thinkwiki, the machine has 4GB soldered on board and one
free SODIMM slot that can take upto 8GB, so it seems like you won't be
able to boost it to 16GB but only to 12GB (tho it's always possible
that the slot can actually take a 16GB SODIMM, even tho it's not
documented and I'm not sure where you could find a 16GB DDR3 SODIMM).

I wouldn't expect any noticeable difference in practice, no.

The DDR4 memory is a bit faster, but I still wouldn't expect any
noticeable difference in practice, no, especially since the X270 only
has a single SODIMM, whereas the T450s has two (one of which is
soldered), which should more than make up for it.

No experience, sorry.  Any chance the reviewer's problems were linked to
software bugs that can hope to be fixed overtime?

For me it would boil down to size (especially screen size), but check
also the battery story (both its capacity and the ease with which it can
be replaced).
Sadly the thinkwiki doesn't have an entry for the X270.

I know exactly what you mean (happy user of a T61 here as well).
