the power book G4 can use the Airport Extreme card.
better off to buy a g4 the gun over all is better in every way the G4 is 1.79lbs on/off asa easy clip feed neck way better at shooting and there is a lot more
DP G4 is definetly the way to go. The proto slg can't shoot as fast, isn't as light, and has way too many problems. The G3 was an amazing gun and all they did with the g4 is fixed the few knicks with it and the G3 was a better gun than the SLG. Plus if you ever do have a problem with the G4 the customer service is amazing. I love my G4 get it now!
Be specific about "good" compared to what standards or other markers.
