Thinkpads generally just work.

I believe as of 4.2 or 4.3 kernel, they should be OK.  I did an install
on a Core i7-6700k a couple of weeks ago, and had no issues.

No the Tx30 was fine, the Tx40 was the problem.  The Tx50 fixes it
(and the W541, since the W550 isn't out yet, but people wanted a fix
for the screw up).

Actually I believe there is a 3 cell battery internally (permanent)
and then an external swappable battery.  Now maybe that internal batter is
in fact where they used to have the optical drive (which I just noticed
does in fact appear to have gone away).

mSATA is obsolete.  M.2 it might have.  As far as I can tell it has an M.2
2242 slot (so 42mm max length) which is limiting, since most cards are 2280
(80 mm length).  It appears to be SATA only, so no NVMe or PCIe cards.

I thought the minimum was 1920x1080 on the T450, but I didn't check.

Only the Txx0p models I believe.
