Hello. I will be buying a Mac for college in the next couple of weeks, and would like some advice. I am torn between a low-end G5 (1.6, or whatever Apple debuts at WWDC) and a PowerBook G4. I've read benchmarks and other data, but if I could get feedback from people who have used both I'd appreciate it. I basically want to know how significant the difference in power is between a G5 and a Powerbook. Also, I will be studying engineering, so I'd specifically appreciate input from any of you doing the same. Thank you in advance for the assistance. Edit: Budget of $1750. Education discount applies. PB Model I am most interested in is the 12".
