I'm pretty sure that Google's Chrome is the slowest browser ever when it comes to using it on a Win7 64-bit. Takes forever to load even seemingly simple things. Common Google. Really.
I read an article today about the new Firefox beta. Maybe I'll use that.
I tried the 64-bit version of IE but apparently Adobe Flash is not supporting 64-bit browsers yet and they tell you to use the 32-bit version instead. Tough luck, go home, do not pass go and absolutely do not collect $200.
It seems that plenty of people are supporting 64-bit versions of Linux though. Or perhaps it's just that the grass is greener.
