Hi everyone. I have been reading these forums for awhile now to help prepare myself for finally making the switch and purchasing my first Mac. I ended up buying a 15" Powerbook. I could not wait any longer to buy since my old Windows notebook was falling apart on me. So I picked up my PB on Tues and so far am really liking it, although I am still figuring things out. I have a couple questions that I was hoping you could help a Mac newbie with. First, is it okay to keep the PB always plugged in through the AC adaptor with the battery in it? Does having it plugged in all the time effect the battery life? Second, I was looking at some web pages with videos in them and when I click to watch the movies opened with Quicktime in the browser window and I could not find an option to make the video larger. Is this possible to do in the browser or is there a way to set it so when you click on a movie link it will open Quicktime separately? Seems like I had one more question, but I can't remember it now. Thanks for any help you can give and thanks for all of those people who post good information on these sites that make the buying process much easier. So far I am really happy and excited about my purchase. I love the backlit keyboard!! Apple is so good at the little details that make such a huge difference!!
