Hello all, I just jumped ship myself from widows to a new 20" iMac Sunday. My son-in-law says I will never look back. Its going to take a bit to figure how everything works. First off I ordered 4 gig of mem to replace the 1 gig that came with it. I have 10.5.4 and and downloading .5 while Im at work. Here are a couple of questions I have if you can shed some light on the problems for me: My mouse seems so temperamental, its all over the screen. I've tried adjusting the mouse settings and it hasn't fixed it yet. Next Im using a hp psc 1350 all-in-one and trying to run it wireless and will not do it. It will work fine plugged into the usb. I did buy the airport express. I have looked on hp website and cant seem to find if their is a particular driver that I need.
