You've got history backwards. IBM Thinkpads did it that way 30+ years ago, when there was no consensus in the industry. Do you switch it now, and anger every lifetime Thinkpad loyalist, or keep it and annoy just the folks who switch back and forth between different vendors' laptops?

In a brief survey of laptop photos from the early 90s, IBM, Toshiba, Zenith, NEC, Packard Bell, Compaq, and Fujitsu all put Fn on the outside.

Epson, Apple, HP, Panasonic, and Sony put it as the second key.

A handful put it as the third key. Heck, one Toshiba machine had Ctrl left of A, Alt on the extreme lower-left starting out the bottom row, followed by Caps Lock and Fn and backslash and finally spacebar.

Only in the last 15-ish years have most of the Fn-Ctrl keyboards died out and the majority of the industry is now using Ctrl-Fn. Thinkpads are the last major holdout, but they didn't decide to buck the trend, the trend bucked them.
