No M.2 slot for SSD in a 12" laptop - is crazy in 2016, there are plenty of PCIe and SATA SSDs these days - and the space could have accommodated a bigger battery and/or 2nd memory slot!

If they really wanted big storage, they could even put two (2) M.2 slots in there, one PCIe+SATA and one SATA and still have more space left for battery. That could even allow for RAID.

Well, I still have my X61s around. 5:4. All space better used. And so many generations later they are not able to do what IBM did with the X61?? As the others said: We want to work with that - 16:10 please! I assume most of the workers are not Excel spreadsheet working...
Battery life is excellent, keyboard still fine it seems. The two klicks for the thumb back (they learned).

no M.2 pci port?

i've never understood the yuge bezels  and the 16:9 format; why not a 16:10 screen on a BUSINESS laptop ?

All that wasted bezel space is sad. 16:9 screen on a subnotebook meant for work is stupid. Lenovo needs a touch from Microsoft / Apple clue stick, to start using taller screens on smaller devices. If history is any guide, they'll eventually get it... after everyone else does. Still love their keyboards, though. And inclusion of a ethernet port.
