You, the beamspring master, don't even have an SSK? I've only got two beamsprings, but more SSKs…
Fullsize keyboards force me to put the pointing device on the left - usually my Magic Trackpad which doesn't need much precious space - while TKLs and 60s let me put it either side, a fact I like to make use of, for load sharing ergonomics.
Trouble is, with the homerow centred beneath my display, fullsize boards are so damn lopsided it feels and looks and I dare say simply is stupid. A TKL is as big as I ever need. No matter the hypothetical conference sized table. My hands and eyes don't like to deviate from the centre line unnecessarily while doing hours of work! Fullsize boards are plain wrong for symmetrical things, like we humans.
