E Bikes and Commuting

As a pleasant surprise, my professional institute mag (Engineering & Technology) ran an article on the impact of electrical technology on cycling.  It covered electronic shifting but most of it was pedal assist bikes and how it was a massive growth area.  Sadly my current commute is primarily a car journey, although I do cycle once or twice a week.  The fast, busy A (or B) road isn't my thing so it's a town, bike path (some gravel) and back lane ride which means it's hard work and takes anything from an hour to an hour 15 depending on time of year and which bike gets used.  I started to ask myself the question whether a pedal assist E bike would be capable of taking the 'sting' (ie the steep hilly bits) out of the ride and up the average speed to make the ride easier to achieve on more than 1 day.  It's pretty knackering and makes the working day quite long when you factor in showering etc.  Most E bike 'chat' is around older people where it has allowed them to overcome age related problems that impact on normal cycling.  Just wondered whether anyone had some 'tales' where an E bike had revolutionised their commute.  I'm not convinced it would make a massive time difference, apart from making the hills more bearable, but just got me thinking.
