Oh puh-leaze. How presumptuous. The fanboys continue to miss the point or are in some serious denial: its a horrible investment decision. Try to rationalize "thin" all you want, but there are objectively superior and more affordable options. So no, until thin doesn't entail paying an absurd premium for a litany of compromises, then I'll happily putz along on my now "roamy," uncompromising, more compact and much more affordable lappy.
But hey, go ahead and revel in your gadget-lust and the conspicuous consumption it enables.
I can see you've never used a thin laptop before.. After having used one for 3-4 years, it makes my MBP (15") seem huge and heavy. The Air isn't for me (no Firewire) but I completely agree with the OP.
