I am finally fed up with Vista so much that the wife and I have decided to take the Apple plunge together. We are looking for a notebook that will be mostly plugged in but sometimes taken to the couch, backyard, or on trips. I have narrowed it down to the MBP but can't decide on options and would love some help. We are looking to use the notebook to edit photos and High Def Videos of our first child (due in Feb ). Probably using iLife and Aperture 2 for the cool feature of being able to make our own scrapbooks and have them printed and bound. I'll be using Garage Band to record some of my original music and of course publishing some websites as well. Were also already using MobileMe with our iPhones and Vista desktop to keep everyone's schedules in order so the notebook will also integrate into this I am sure. Besides that the machine will be used every day to browse the web, e-mail, and whatever else cool Apple makes easy. So on to my questions that I would love some answers to if possible: 1) Coming from the Windows side, I found myself upgrading desktops at least every 12 months and laptops within every 24months. Does a Mac run the same lifecycle or can I expect to be using this product for 3-4years to perform the tasks I mentioned? (I.E. do the upgrades to the OS usually install on the current models and run ok) 2) CPU, RAM, HD for best performance in the applications I mentioned, is there a minimum I should be shooting for? (I hear 7200RPM HD is going to be key for photo and video editing and RAM up to 4GB is suggested but the CPU doesn't really matter as much) 3) I am considering the 17" model over the 15" unit just for the sake of having more real estate to work with. Any thoughts on current owners for or against the bigger screen? I am still not sure if I will wait or take advantage of some sales with rebates I see from places like Amazon or Apple Refurb. Thanks for any input. **By the way, I owe all of this madness to a friend gifting me an Ipod touch 6 months ago. 2 touches, 2 Iphones, and now soon to be one Mac later. Here we are. Some would call it a virus, I would call it enlightenment.
