this is a personal taste question...as well you are asking in an OS specific forum.
That said, you should get a Windows Vista based laptop
Macs can get virii/malware/trojans, etc
If you're not a true techie and do not like to tinker with your computer, pic a Mac. If you like to mess around, buy high end gaming gear, and tinker with your computer, stick with MS.
Since this is WINDOWS OS...you should just check with MAC sites or the mac forum. Then see what is better for you.
There are some people who hate Windows and will come here to make negative commments. That I don't understand....but of course sort of do. I don't care about mac, linux...and I don't need to say anything against them...so I don't.
You will often find though that, Windows fans have the ability to be neutral and/or fair. That is, if we don't use something...we won't say we don't...but then bash it.
