Time for my rambling opinion here; Nothing is wrong with your computer, or your ram allocation, or your processor, or your OS, or your browser. It seems to me that whenever someone is having trouble with a web page, (or a "web community" such as MySpaces, ebays, yootoobs, etc...) they always take the blame on themselves or their equipment. While there are plenty of problems that we bring on ourselves, it is not always the case. When everyone is having problems with MySpace, wouldn't it seem logically true that the problem lies more with MySpace than with it's users? What if all mac users quit using myspace overnight? I'll bet a larger percent of Mac users have been to MySpace than peecee useers. Write to the administrators (of Myspaces) and complain about compatibility issues. Contact technical help desk to let them know that there is a problem. Let them know that macusers are not willing to accept the discrimination. (Tell us why we should be punished for using a mac?) It is not the fault of Apple, or the users of Apple products that anyone else does not step up to the technical plate and make their systems cross platform compatible. Apple has done more to accomodate the Windoze world than M$ has done for themselves. Programmers have become lazy because hardware is so much more advanced, and is becoming more intuitive, so programs don't have to do as much as they once did. ...BUT, I am rambling here.
BOTTOM LINE = You are good, your mac is beautiful. The others only put you down because they are jealous.
