I dunno why you guys think 101 is the "old school" layout.
The Sun Type 4 has (going left to right, spacebar row) Caps, Alt, Meta, Space, Meta, Compose, AltGraph.
The IBM RS/6000 InfoWindow uses a 3270/5250 (F1-24, rule key, left deadkey, etcetera.)
Reason I don't like the Windows key is because it's just a bad design for fast typers who frequently use Ctrl or Alt modifiers. If you accidentally hit the Windows key midflight, yeah, bad things can and do happen. My preference is pretty much exactly as SteelSeries did on the 6GV2 and Thermaltake on the Meka G1; Fn/Layer Mod with no Windows key map on the left. Especially mapped to media controls or programmable layer. But that's just my preference.
