I tried Chrome last year and can't recall the cons now but I didn't like it.
Computers are really weird and all differ. My laptop only works well with Firefox. I've had others tell me they had to go to Firefox because of trouble with MS Explorer.
But if Explorer works well then I prefer it over all the others mostly because of compatibility online. Some site features just don't work in Firefox and I would think that's probably true with Chrome too.
The nasty old MS company is pretty hard to beat when it comes to any form of software. I guess it helps having a million dollars to every competitor dollar.
