I am considering buying one of these new 23" iMacs if the rumor happens to be true. But I'm not so willing to be paying for Apple's RAM, while better than it used to be, it's still a tad bit high. How hard is it to add ram to one of these new iMacs? It was a breeze on my PB but if it's really hard on the iMac I'll just bite the bullet and go with the 2gig straight from Apple.
