Trying to decide between 1.5 ghz 15" PB with combo drive v. 1.67 ghz with superdrive. I've never had a dvd burner, and I'm not a videographer (my only "video camera" is in my camera and my cell phone). I use computers for word processing, email, photos, music, web, simple spreadsheets, taxes, family tree stuff, accounting, and the like. Any work I would do on it would be in Word. I treat it like a tool. Thus far, I haven't had a need or desire to spend a lot of time to, for example, create a dvd of something or another for handing out to people (no kids, or wife for that matter; no one wants to sit through a dvd of my travels; etc.). I'd back up to an external drive instead of dvds. On the other hand, maybe I'll have an explosion of creativity once I'm exposed to a Mac? Thanks!
