I just bumped my dev machine's memory (which is also hosting this blog) from 1 Gig of RAM up to 4 Gigs RAM.
For the past few months, I would spend a majority of my time with 1 - 1.5 Gigs memory in use, which meant constant swapping to the page file (slooooooowwww).
Now with RAM quadrupled, I can cruise at 1 Gig memory in use without needing to even make a cursory glance over at the page file for approval.
I think this merits a "Squeeeee!"
