Apple commands a hefty price for their products, but they also give you a good value for your money. I've owned a new macbook since early November last year, and I couldn't be happier with a notebook computer.
By making the laptop enclosure out of a block of solid aluminum, they've built in a level of structural integrity I've not seen in even tbe best ThinkPad, my previous 'gold standard' for laptops.
There's nearly nothing I do that I can't get done natively in MacOS. I also run VMWare Fusion for MacOS, and have a Windows XP VMWare image for those occasions when only Windows will do.
