With so much different stuff average user is connecting and installing, I concluded that PAE is limited to specific environments and users. There would have to be a real need for it to cancel out the fact that there will be more problems on average when using PAE. Over the lifetime of the machine, the sheer amount of time needed for experienced user, let alone a less knowledgeable one, doesn't make PAE attractive, in my humble opinion.
However, if you set a few things for a long-term machine environment that doesn't change much, sure, maybe in that case, but for always changing home use?
Even a full blown 64-Bit OS (unless you are putting your machine to sleep) I figured was not worth it for me until Windows 8 comes out at the earliest, so it's a matter of personal use, always coming back to the same question: If not for a professional graphics machine or for a folding machine, which program capable of frequently using more than 4GB of RAM do I use regularly to justify 64-Bit Windows? Not a single one. And there is no other advantage to 64-Bit, unless like I said, you are a user who puts his machine to sleep.
