Google Chrome is now 2 years old and has already hit version 6. That’s a much faster release cycle then any other browser out there.
Google chrome 6 brings extension sync to the masses, as well as a boat load of security and memory corruption bug fixes.
Personally I think Google Chrome is great but Google release cycle of a new version every 6 weeks means we could easily hit version 15 before IE9.
Google has yet to fix (or deal with) memory issues resulting from flash (high memory usage compared to Firefox/IE), and Java issues (Pogo still doesn’t work…).
Google chrome has a 7% market share so it’s not as popular as Firefox but it is dwarfed still by Internet Explorer.
I’ve personally used Google Chrome for a while but since my laptop only has 1GB memory I cant use a browser that uses that much memory (Safari is like that too), that’s why I use FireFox because it uses by far the least memory.

Just wondering what browser you are using most of the time? I’ m using Chrome, but it appears it really eats RAM – let’s say when 10-15 tabs are opened. I think that’s one of the areas they should improve….
I’m using Firefox 4 Beta 4. Chrome like Safari will eat up your RAM because it doesn’t scale well (blame flash).
