Getting a new laptop?

Hi I am looking to get a new laptop. I have played on an apple thus far and I am ready to branch out to sites away from the pokernetwork (ongame network). I am looking for a little bit of info. about where to buy and what to get. I will be at least 4 tableing on the laptop but I will use it for almost nothing else besides poker. I see deals posted on here frequently..where do those come from and should I wait for one of those to come up again? What is the best laptop to buy- dell? Any information would be greatly appreciated as I know very little about the subject. I am sorry if this is a noob question or if I should have posted it in a different forum. Oh and I have plenty of money to buy one with but would not like to spend more than necessary. Thanks for any help that you can give.
Z.P.
