it's 34. There may be a CF reader, but it won't be internal.
Always waiting for something to come out
don't sweat it, get one of the little lexar firewire readers. And get one of the short, thin, limp firewire cables they sell at the apple store, 1/2 meter. Great for travel. I have one and carry an ipod adapter and a 6 pin to 4 pin adapter for it.
I agree with Roger. As I carry 12" Powerbooks (no PCMCIA), I've always used Lexar FW readers which are cheap light and reliable - I carry a couple. The iPod (bought when I ran out of hard drive) is an excellent if expensive additional backup and is easily carried in a shirt pocket withh a lot of images on it at the end of a trip.
Alternatively, the new Sandisk Card readers using ESP are almost as fast as the lexar and use USB2.0. I use the 12 in 1 since I use SD, CF and Duo. I get 13-15mb/s downloads on a PB G4. It's even faster on XP for some reason.
