Early adopters are generally the least loyal of any customer. They are much more likely to take a risk on new technology and give it a shot.

Just an anecdote, but I have been using chrome for the last six months because everything else was slow as a dog on my Mum's MacBook Pro, and chrome was super-fast. But the lack of decent keyboard link navigation is driving me crazy, and may drive me back to firefox soon.

Interesting, I've found Chrome to be slightly faster than Safari on my MacBook, but also much more prone to stalls and complete catatonia than Safari.
