for the ipod offer, you NEED to purchase the macbook all together. for the printer rebate, you may purchase it later (before the deadline-but ask apple when you visit just to make sure). make sure you make a copy of your UPC code on your macbook case because you will need it for your printer rebate along with your ipod rebate.

i was also a life long windows user and it only took me an hour to adjust to the new mac operating system. it is a bit awkward at first but you will realize how complicated windows is. your macbook should have about 2 hours of battery life when you first turn it on. programs and softwares are already installed so no need to worry. just turn on the computer, answer a few information questions and voila! and the airport (wireless internet built in macbook-performs well) will pick up nearby signals and you can possibly use neighboring wireless connection if they don't require a password. if there are no signals, you need to invest in a wireless router ($50-$150). instead of purchasing online, visit your local best buy or compusa and ask them about it. they are usually knowledgeble about this subject. it is very easy to install. since the macbook has wireless card built-in (airport) you do not need to connect the ethernet cord to your macbook. it works wirelessly. so basically, all you need is a wireless router. no need to sign up for stuff if you are already a member of a dsl.
so...you open your macbook, turn it on and type in some info, your macbook will ask you to download the new updates which takes maybe 30 minutes? i forget. then, for now (since you do not have the wireless router) you can connect the ethernet cord and you are internet ready! so total of 40-50 minutes? and to get familar with your macbook, it should take you one hour approx. 🙂
when i first joined a month ago, i was also a mac noobie but through this forum, i became well knowledged and it is a great feeling to help out people here because i, myself, had a great experience here.
hope this helps! and good luck!
