When Apple first released force touch (3D touch) just over 2 years ago the reaction was almost like they had re-invented the wheel, even though to me it was a glorified right click. I used it this morning, more by accident than anything else and it got me thinking how many people might have bought the iPhone 6s just for this feature (based on Macrumors at the time, there were quite a few lining up).
So, what devices have you bought in the past for a feature(s) plugged at launch only to rarely use it, if at all?
