Hello, I have a Mac Mini 1.5GHz G4, 1GB RAM, 19" wide screen monitor, and a PC laptop. I was wondering if I should sell all of my stuff and buy a new entry-level Macbook when they come out on Tuesday. Would I see much of a performance difference? The most processor intensive application I use is HandBrake (ripping DVDs). Otherwise I code XHTML and CSS and Java Script, watch movies, rip CDs in iTunes, and use iLife (iMovie 06, iPhoto 08), and I use Photoshop for batch process of images for photo galleries. I know I'll need too upgrade sooner or later, so why not now!?
