What about new Powerbooks? Is i just me, or are the powerbooks a little outdated (in terms of speed). When are new powerbooks coming out? What do you guys think? All i think it needs is an updated chip: like 733 and 867. That would be a nice upgrade. also if the resolution could be a little higher, and please: a new graphics card! what about a new Geforce 4 Go chip? What do you guys think?
