Think back to new products or services you have experienced.
What was the stimulus for their creation.
Intermitten wipers. A better and safer driving experience in light rain.
Stoppers on skis. I can remind having a strap around the ankle, which would snap or come lose. You'd fall over and the ski would vanish. Safer for people who used to be hit by skis ... though you still lose a ski a deep snow.
Contact lenses. Vanity. No more glasses to fog up. Sport (especially swimming). A market.
Amazon. Thought I was saving money by not shopping on the High Street at Christmas only to spend far too much online. The new way of doing things.
PayPal. Convenience of online payments. A need.
iPad. Online 24/7 Tried tablets before and failed, this works.
Kindle. Using 'The Swim Drills Book' and showing young swimmers images on the Kindle by the side of the pool. Reading The Isles by Norman Davies and able to carry it about. I'd like an A4 size version.
Sony Alpha digital camera body. It takes Minolta lenses I bought 25 years ago. Brilliant.
Brushes: iPad App used by David Hockney for 'painting'. It works. Brings painting and drawing up to date alongside wordprocessing.
