My (what I like to consider to be) non-biased point of view:
As a satisfied new MBA owner, who has never owned an Apple product other than an iPod by the way, I will never, ever purchase a computer based on specs without using it ever again.
I very rarely see it discussed around here, but my favorite thing about the Macbooks is the trackpad. Obviously this feature is not unique to the Air, but the awesome trackpad (size, responsiveness, gesture integration, etc.) makes using this computer so fun and easy. The trackpad on the Samsung looks bigger so maybe they are trying to emulate the Mac in this regard, but others have tried before but in my opinion they haven't come close.
I played with 20 laptops before settling on the Air, and really, for my usage (think standard MBA user profile), the trackpad seriously became the most important differentiating factor. I feel like that will sound ridiculous to a lot of people, but it really is amazing to me how much the trackpad affects the user experience, and even the most advanced Windows machines I have used feel totally clunky compared to the Macs.
The bottom line is that the numbers do not tell the story. Take this thing for a test drive before you declare the death of your new MBA!
