I was looking to get a powerbook, 12 for presentations for school. I would get an ibook, but i need the mini dvi out. Originally i was looking at finding a used current 1.5 model, but as its a second machine, i don't want to spend too much on it, they are going around 1200 avg. on ebay. So i was looking at the 1.33ghz model, i could get one for around 1000. I'm guessing i won't really notice a massive difference between the processor speeds. But there are some things that i do need, and want to know if they are standard. I want to know if bluetooth and airport are standard on all 1.33 ghz models. I want to know if the video cards are the same. and finally, since i have a 1gb stick of PC2700 ddr ram, i want to know if that is compatible with the 1.33 ghz model. Any help would be appreciated, as i kind of need it soon.
