to mac or not to mac

For the past two months, I have been actively looking for a notebook computer. I found one that seemed to be a bargain. It was the Lenovo X200 Tablet. I was supposed to wait for its delivery for a month, because I ordered it before it was officially launched. To my disappointment, I found out that the model that I ordered did not include a touch screen that can be used with bare hands. It required a digitizer pen. This is a reverse in technology on lenovo's part. So after a bit of persuasion, I finally got a refund arranged. Yes, in Hong Kong, where refunds are not common. Anyhow, this brings me to my current dilemma: to mac or not to mac.

The timing has actually got me thinking of the possibility of getting a MacBook. Previously, I didn't choose it because it was outdated for the price, but now that it has just been updated on Oct 14, it got me thinking.
Looking at the specs, whether I should pay the premium of 40% for the aluminum chassis, glass multitouch touchpad and cleaner design.
Performance wise, I would still lack the power of a dedicated display card.

If I were to spend the same amount of money, I would be running a notebook that seems better in performance:

Bigger screen at 15.4" with better resolution, 1920 x 1200
Quicker CPU at 2.53ghz vs 2.4ghz at double the Level 2 Cache
Extra Card Reader, Express Card expansion and Firewire (IEEE1394a) port
I can even get HDMI and Blu-ray disc player.

Of course, there is also the trade off of an extra 0.5kg and 1 hour less battery life.

The Mac OS is also a mixed bag. Surely it may be user friendly and looks nice, but it requires it own set of software. Running both OS X and Vista on a Mac is an option, but should I bother?

Will the experience grow on me? Is there more to it for using Mac?

Should I trade performance for style? Or should I go further to save my $$$ by getting a PC with Macbook's specs?

To Mac of not to Mac, that is the question.
