I am debating whether or not to switch to Mac and buy a new Al Powerbook. I am a graduate student and will mostly be using it for assembling presentations (what is the Mac equivalent of Powerpoint?), word processing, internet surfing, music, and DVD's. Also, from anyone who has compared a new PB LCD to, say, a high-end Dell or other PC LCD with a higher resolution, which screen looks better? I know that the PB's don't necessarily have as many pixels (1440x900 for 17" vs. 15" Dell with 1920x1200), but do the PB Lcd's still look just about as crystal clear? Thanks for any advice.
