Powerbooks

Hello I just orderd my 15" Powerbook with Ipod for Cram and Jam ))!!!!
I was wondering is there anyway I could hook up cable from the tv to my laptop screen so I could watch tv on it? On the back of my tv their is a wire for cable and 1 for power is their an adapter or something that I can connect the wire for the cable to watch on my 15" Powerbook Screen?

The PowerBook comes with S-Video and composite video out, meaning you cand send video from the PowerBook to a television, but not the other way around.

At least, not without an add-on like this http://www.elgato.com/

Quick Question: Do the ibooks or powerbooks have a microphone jack?

Powerbooks do.
I don't think all models of iBooks do but you will have to look at the spec sheets on that

According to the manual that came with my Powerbook, they only have a line-level input... not a mic-level one. They do have a mic built into the case, though.

Is the built-in one any good?

I use the built in one in classes with Word 2004 recording and it works great for me. I use the voice chat in iChat when i dont have my iSight and i am perfectly happy with it

Yeah seems to work pretty good for me also.

I'll tell you on Monday when my replacement arrives

I've always preferred headsets, especially for talking over the Internet which I find useful sometimes... however I've never had the pleasure of trying a built-in mic on something as high quality as a Mac so will have to see.
