Agree 100% with you. All we have to do is look at the Opera browser with their Presto rendering engine to realise the truth of this - it really rattled Internet Explorer and Microsoft with its super fast rendering speed and small size that made it easy to download on slow connections. It made Internet Explorer and Firefox look like clunky and slow bloats of software. Opera was so good that they were able to charge for it, and despite the free browsers available many people bought it.
