I have a fairly good windows 7 machine. 64bit, 6gb. I opened g+ in chrome and it crashed, twice.

There are pop overs everywhere I move my mouse, making it even slower! I have a resolution of 1024x768 so everything is squished and hard to find/read.

I'll keep giving it a go, but I do wish they would add a 'lightweight' version, like the html only gmail for us people without top of the line machines that can run crazy amounts of javascript.
